QUESTION 330: Speckle in SAR images are usually modelled by a multiplicative noise model where the intensity (power) has a negative exponential distribution. For complex images, the phase is modelled by an uniform distribution between -pi and pi. We know that in cases where the sampling frequency is higher than the system bandwidth, speckle is correlated between pixels in the resultant intensity image. If I have a complex image instead, would the phase also be correlated? Any response or reference would be greatly appreciated. Thank you. 6/11/96 - 0 responses

QUESTION 319: We have used the CVERT2 software to convert sir-c slc to data in airsar CM format in order to process them into PCI polarimetric radar module. We have used PCI programs to generate the 10 channel of the scattering matrix. By viewing the dynamic range of the HH, HV and VV polarized power (8 bit), we realized that there is an unknown scaling factor. For example, the dynamic range of the hh image was 23.4 - 38.6 over an agricultural site. We also looked at the header of the converted data and found out that the "comp scale factor" was set to 1.0000. Obviously, the power values displayed in the polarimetric signatures are also scaled. Where can we find any information about this scaling factor? Can we remove it easily? 5/27/96 - 1 response - [last response 5/27/96]

QUESTION 301: I'm attemptng to develop algorithms (as automatic as possible) for an oil slick detection that uses Radarsat SAR data, although probably not exclusively. One of the problems to overcome is differentiating between natural oils put out by organisms (fish, algae, etc) and man-made spills. Another is the fact that wind and rain shadows have the same signature. Also, the damping effect on the capillary waves which makes the slick visible only occurs over a narrow range of wind speeds (~1.5 - 13 knots). If anyone could offer me any advice as to how to proceed in this relatively new area of research, or could point me towards any papers written on this subject, I would be extremely grateful.

QUESTION 226: SIR-C collects only high incidence angle data, right? That is, the reflected signal has to bounce essentially straight back to be detected. Now Magellan obtained low incidence radar data by glancing a reflection from the Venetian surface back to Earth for detection. The January 5, 1996 issue ofScience asserts that low incidence radar data contains information not accessible otherwise, here, enough to interpret specularity in the Maxwell Montes highlands as tellurium frost. My questions:
  1. What new sorts of information does low incidence radar data contain?
  2. Is there terrestrial low incidence data, what was it good for, and where can I find it?

QUESTION 216: The cross-range doppler bandwidth of resolution cells in SAR imagery is often lower than the doppler spreads measured for the internal motion of various kind of vegetation. Does anyone have a good explaination why the returns from trees in SAR images do not spread out over many resolution cells and lead to poor quality images? My calculations indicate that in mildly windy conditions the return from an isolated tree should be visible in 5-10 cells to either side of the tree. Obviously this result is specific to one system (x-band 1.5m x-range resolution) The doppler bandwidth estimate for the tree canopy comes from several different sources and exceeds the resolution cell bandwidth by a factor 10. 1/24/96 - 3 responses - [last response 4/25/96]

QUESTION 210: The SIR-C calibration article by Freeman et al. (IEEE Trans. Geosci. Rem. Sens. 33: 848-857) shows various calibration uncertainties for the 2 SRL flights (tables 8 and 9). For instance, the pass-to-pass uncertainty at L-band for SRL-1 is +-1.3dB. How exactly should this uncertainty be interpreted? Is it a confidence interval so that one can assume, for instance, that backscatter from identical targets at the same incidence angles on two different passes will be within +-1.3dB 90% of the time? Or 95%, or 100% of the time? Is the calibration uncertainty to be interpreted differ- ently for point and distributed targets? Also, is the co-pol to cross-pol amplitude uncertainty equal to the sum of the HH/VV amplitude imbalance and the HV/VH amplitude imbalance? 1/18/96 - 2 responses - [last response 2/11/96]

QUESTION 187: hi, Although L-Band Synthetic Aperture Radars have been used to produce high quality images, has there been any attempt to use the Ultra Wide Band UHF. In an earlier paper I had argued that with large band width avaliable, the number of independent samples that can be averaged are high. Consequently averaging these "indepentent samples" can produce a sharper image, even when the entire aperture is not used. (ie smallest possible resolution is not used). I was looking to see if there had been similar work done at UHF for foilage penetarting, imaging radar.

I have concluded that the following procedure is usually used ; location of image pixels, geocoding, mosaicking. In terms of an algorithm implementation, I have some questions. 1) In the location procedure, how can I get Doppler frequency of each pixel. 2) In the image rotation, the rotation angle is said to be determined by inclination of the obital plane & latitude of the scene center. What does incli- nation of the obital plane mean? 3) I want to know the format and the contents of platform ephemeris data and raw data hearder. I'm sorry for my ignorance.

QUESTION 166: I have a basic question about how radar interacts with the ground. I know that as surface roughness increases, less radar energy is specularly re- flected and more is backscattered to the sensor. Is it the same for soil moisture? Specifically, as you reduce soil moisture, do you get more specular reflection (I know less energy is scattered back to the sensor, but is this due solely to soil penetration?)? Also, how would the response vary between HH and VV polarizations? 11/10/95 - 3 responses - [last response 12/ 5/95]

QUESTION 129: Hello; I have a student who has a question I cannot begin to answer. If you could help him out I would appreciate it. I will let him type the question in. Dear NAS, I have heard NASA scientists saying that they plan to terra form Mars by pumping gases into its atmosphere, like CO2 to worm the planet.. But when Mars had an atmosphere before and it wass maintained by volcanoes pumping necessary gases into the Marsion atmosphere. Then when the volcanic activity stoped, the planet lost its atmosphere to space. So the planets gravity was too weak to hold on to any life sustaining atmosphere. Doesn't that mean you can not terra form Mars? Mars's gravity is just too weak. Also, please don't give me an explenation on how you plan to terra form Mars. Just please tell me how do you plan to keep in the gases you pump out from being lost in space from Mars's weak gravity? 9/25/95 - 2 responses - [last response 9/28/95]

QUESTION 116: I am a grad student relatively new to SAR research, so I apologize in advance if this is an ignorant question. My only experience with SAR imagery is over land, (esp. wetlands). In some cases I have found strong sigma0-VV responses over wetlands at large incidence (~40°). I thought this may be due to vertically oriented vegetation growth until I saw the same strong sigma0-VV at large incidence over open ocean. I expected calm ocean to be nearly specular, with sigma0-VV roughly equal to sigma0-HH. I thought my image might simply be a special case with waves oriented to produce the strong sigma0-VV until I noticed that in some references, (Ulaby, Moore, Fung, Microwave Remote Sensing..., vol. 2) that sigma0-VV is predicted to be stronger than sigma0-HH at large incidence over ocean. In this reference, nothing was mentioned about a particular wave orientation. So what is responsible for the sigma0-VV response that I get over the ocean? 9/ 6/95 - 1 response - [last response 9/ 7/95]

QUESTION 92: I'm a UC Davis water management specialist working on something called regulated deficit irrigation. It's the practice of purposely depriving plants of water during stress-tolerant periods in order to save water while possibly enhancing some aspect of production. For example, we identified that mild stress during late July in almond can reduce the incidence of hull rot fungus. I have 3 experimental field sites in the San Joaquin Valley where different irrigation treatments result in tree water stress. We are monitoring this stress from the ground with leaf/stem water potential and stomatal conductance measurements. I would like to see if these stresses express themselves in something that can be remotely sensed. I've tried using hand-held infrared thermometers from 12 ft ladders to monitor canopy temperature but there is a lot of variability. I'm thinking something from an airplane would be much better. Each replication is approximately 75 x 120 ft. and contains 8-30 trees. I believe there are some private consultants who offer fly-over services using some type of infrared film. However, I've never been satisfied that they know what they are measuring. This would be an ideal opportunity for someone working on developing remote sensors to verify their utility with ground based measurements. 7/24/95 - 1 response - [last response 7/25/95]

QUESTION 54: This is in reply to Tom(?) who replied to my question no.51 I/we don't have a homepage and your e-mail address appears to be invalid so... Our radar is 94GHz (sees through fog/rain/smoke) and has a 25cm down-range resolution. The cross range resolution is between 1.4m and 4m at 800m range. The data is digitised to 8-bits and yes we fly our own helicopter over what we fancy. Yhis uses most of our buget and the cost per mile is frightening, so I'm not at liberty to hand out free data (sorry). We have automatically registered these images against cartographic maps and x-band SAR. To do the same against infra red images would be harder because of the lack of range information but it is possible.

QUESTION 52: I work with imaging radar. A forward looking airborn radar scans the ground from +/- 30 degrees at a shallow depression angle. The data is gathered at about 800m. A radar image is made, combining the information from many sweeps. High down-range resolution plus the use of doppler beam sharpening techniques allow the formation of good quality x-band images. We then aim to automatically register these against cartographic maps and also identify interesting features. Is anybody interested in this sort of work? 3/29/95 - 4 responses - [last response 10/19/95]

QUESTION 48: After finding the data take for a SIR-C image, I tried to browse and view several images. The host connection was taking far longer than I thought it should, so I stop transmission. Should it take longer than several minutes for host contact wh en trying to view or browse SIR-C images? Thanks, Scott Hughes hughscot@isu.edu 3/17/95 - 2 responses - [last response 3/27/95]

QUESTION 34: I keep hearing rumors of a third flight for the SIR-C radar. Rumor has it will fly with an extended arm of some sort that will have a receive only panel array. Is the third flight on the drawing board or just rumor? And what is the purpose of the receive only array on the extended arm? Final question when will the SIR-C images come out on CD-ROM and how can I get one? Thanks Bruce. 2/16/95 - 3 responses - [last response 3/27/95]

QUESTION 32: Some comments: 1) How about an imaging radar 'who's who' with information on research interests, possibly brief biographical details, and a contact address. This would be a useful resource for researchers. I mean this to include anybody, and not just limit it to the JPL staff. 2) I would like to see the standard sample datasets available via the WWW route. One of each format, from each sensor would be nice. 'Real' data, rather than pictures, of course. Ditto the standard docs, preferably in postscript format. 3) A list of available JPL radar reports/publications along with ordering info (etc) would be useful. This would stop me having to bug the radar librarians so I guess they'd be happy too. Perhaps a section on radar textbooks would be a useful item too. 4) Finally, congratulations on the BBS and the updated home page! Rick 2/15/95 - 3 responses - [last response 8/ 3/95]

QUESTION 30: I am doing thesis work comparing shuttle visible imagery with radar data from SIR-C, preferably taken at the same time.

QUESTION 28: We are interested in looking at the radar images on our Mac, however we seem to be having some problems. The documentation says we can view images on a Mac with either Photoshop or NIHimage. Neither of these work on the *.IMG file we have downloaded. Is there some translation process that we have missed? And, if so how do we view these images? And where can we get the appropriate software from? 2/ 9/95 - 2 responses

QUESTION 24: The novel aspect of the SIR-C and AIRSAR data sets is the polarization. If it were just another 3 wavelengths added to IR and visible data layers, we would all know what to do. My question: is there inter-band statistical correlation of polarization and how do I remove it? That is, how is principal component analysis done in this context: do I remove inter-band intensity correlation separately or somehow simultaneously with polarization correlation? Your reference section is under development and still fairly sketchy -- has this been done already? 2/ 5/95 - 3 responses - [last response 3/26/95]

QUESTION 15: In posting comments or responses to the bulletin board, may we include links in our documents? Or would JPL rather edit these in or forgo this entirely? As an experiment, I am going to include a link to the radar image data warehouse at Eros, the Eros Data Center (EDC), in this message. If this works, my method was to simply imitate the html formating used for links when the bulletin board is 'viewed as source' in the Netscape browser, pasting in Eros' URL from my hotlist. 1/28/95 - 8 responses - [last response 3/26/95]

QUESTION 07: The current (2/95) issue of Scientific American contains a short piece (Pp. 18) on JPL's collaboration with French Scientists in the development of radar "interferograms" for use in mapping deformations in the earth arising from earthquakes. I'd like to know the technical details of the technique. Have there been any publications, or are there materials available on the WWW that will help?
