there is no dark side of the moon (though there
might be spots within craters or near the poles
that never get any sunlight). There is a far side
of the moon, though. the far side of the moon was
mapped by the clementine mission a few years ago,
and of course, there are maps from the apollo
missions.

"Remote Sensing - Principles and Interpretation, 3rd edition"

He contains some excellent geological case studies using radar for structural situations under dense tropical conditions.

Mainly this, the radar can penetrate the forest, and the geologist can interpret for the purpose of oil extraction.

Attenuation and scattering of radar waves in the
troposphere will occur mostly at the higher
frequencies only and only in heavy rain. The
weather radars we're familiar with from the TV
weather report typically operate at less than 1 cm
wavelength, so a K-band radar would have some
trouble operating through heavy rain. We have seen
attenuation and scattering in SRL X-band and even
C-band in a few places in South America- it must
have been really raining to show up at those
wavelengths! A more important problem is the fact
that tropospheric water vapor causes phase delays
in radar waves, independent of frequency. This has
shown up recently in repeat-pass radar
interferometric images. The only way around this
problem is to acquire many pairs of radar images
and hope that the water vapor effects can be
averaged out. There are many references on this
subject- check out the references under the
Science and Applications button.

QUESTION46

46-1
NASA is planning a NASA Research Announcement,
probably in the fall of this year, for proposals
to use digital topographic data in scientific
studies. Among the data to be announced as
available for these studies will be SRTM digital
elevation models (DEMs). There are no plans
currently to distribute any other data from SRTM
(eg. raw or complex interferometric data).
However, if enough users request it, NASA may
change this policy.

In addition to the C-band system which will
produce the global DEM, the German space agency,
DLR, will be adding a second X-band antenna, which
will collect 50 km swaths over much of the earth.
DLR is currently working on their own Announcement
of Opportunity for X-band SRTM data. I don't know
what data will be covered in that AO.

We hope to make the SRTM web page available to the
public in the next few weeks. It's been under
development for several months, and is now near
the end of the approval process. I will announce
its availability on various news groups. It will
be found on the Projects page of this web site.

QUESTION31

31-1
There has been some modeling work on this, but I
don't have any references handy. Attenuation is
not too bad, but phase delay is. The problem is
stronger at lower frequencies, say below a few
hundred MHz. For that reason, we decided that P-
band (400 MHz) polarimetry from space was probably
not possible. Phase delays at higher frequencies
do show up, though, in repeat-pass interferometry
and in GPS. Some researchers have interpreted
differential phase delays in radar interferometry
as variations in the ionosphere from one pass to
the other. You might look for a paper by Massonnet
on artifacts in interferograms. The GPS guys have
worked on this for some time (they operate at L-
band), so there are quite a few references on
that.

I'm not sure there will be a big difference
between a quiet sun and active sun as far as these
phase delays are concerned.

Sounds iffy. Available satellite imagery is just\
too coarse to identify things even as large as a

However, since these guys rarely go down without
some help (i.e., trees and limbs), you may be able
to look for trees in the right-of-way. Still, I
think the resolution just isn't there. Aerial
photos are a different matter, but somewhat
expensive, and require good weather. Assuming you
have an idea where the problems might be, you
could limit the search area and save $$. Contact
some local aerial mapping outfits and see what
they say.

If you pick up a current issue of a magazine like
"Sky and Telescope" or "Astronomy" etc. look for
a small add in the back on sattalite imageing. It
offers software that allows for the reception of
sattilite imaging information used by NOAA. All
that is required is a computer, the software and
a short wave receiver. It allows for real time
imaging as well as a composited view to put it in
aparant motion. If memory serves it is not that
expensive. You can pick up a short wave receiver
at Radio Shack.

Hi,

I think you are an experienced engineer in SAR
signal processing. I also have great interest in
this area. However, presently I have no such raw
data as you used and I'm not experienced in multi-
look processing. Perhaps now I could not give any
effective suggestions. But if you agree, I would
like to have your sample raw data and process them
together. If available, please let me know:

r_hu@hotmail.com

Best wishes!

multi-look processing refers to averaging in the
along-track or azimuth direction only. This could
be the reason why your ENL SEEMS to increase by
the sqrt of the new multilooking. It has nothing
to do with averaging pixels in the range direction
or slant to ground conversion.

BTW: I know nothing about SIR-C.

Hi,

I haven't had worked with SIR-C data before,
nonetheless the principle of "multi-looking" is
the same in all SAR images.

Multi-looking is a process where n different
intensity measurements of the same object are
combined to form the incoherent average. This is
achieved by dividing the available doppler
spectrum into the required number (n) of
non-overlapping segments and processing each of
its own separate intensity image, which are then
averaged...
I = 1/n (I1+I2+....In)
"multi-looking" preserves the local mean of RCS
and at the same time reduces the variance by a
factor equivalent to the number of independent
looks. ENL then is equal to /var.

If you are working with slant range Complex
product, the geometry is distorted relative to a
map projection but each measurement corresponds to
the actual SAR measurement (subject to calibration
correction in processing of course). You could
either resample the data to ground range and
project to correct map projection, or average
pixels along the azimuth with the result close to
correct geometry.

I refer you to Prof Shaun Quegan of University of
Sheffield for details on this subject.

Years ago I worked for the Air National Guard in Montgomery, AL. It was a recon outfit that ran a lot of T-11 and IR practice runs over NW Florida. I understand that Egland AFB also uses the area for practice sorties. You might try contacting the ANG in Alabama. At one time they also obliged research interests by running their practice sorties over selected targets. They have to have so many hours flight time and a certain number of practice missions per year anyway.

It's something having to do with convecting
atmospheres. I'm not too sure myself, but perhaps
you may be able to look up some stuff on
convecting atmospheres and see what you can
find...

The adiabatic lapse rate has to due with the
deviation from standard that the atmospheric
temperature decreases with altitude.
1/29/99

64-2
Lapse rate - change in temperature with altitude
(i.e., positive lapse rate means it gets colder as
you go higher in the atmosphere.)
adiabatic - without adding heat (i.e.,
thermodynamic process that considers only change
in temperature, pressure and volume.)
adiabatic lapse rate - change in temperature with
altitude when no heat is added.
The adiabatic lapse rate is thermodynamicly
determined by the temperature, pressure, volume
and humidity, so it is possible to measure those
things at the surface and predict the change in
temperature when an imaginary parcel of air is
lifted adiabaticly. If the adiabatic lapse rate
is higher than the environmental lapse rate
(measured change in temperature with height (by a
radiosonde balloon for instance)), than the parcel
would be warmer than the surrounding air. In that
case the atmosphere is considered to be unstable
and convection is likely to occur. This is a
barebones presentation, so look at a good
meteorology textbook for a complete presentation.
(Try Holton for the equations.)

QUESTION80

80-1
A flooded region will look very dark on a SAR
image. This is because the water surface is
smooth and very little of the incident energy is
returned to the radar. Dry land will have some
roughness to it and will look brighter on a radar
image. The level of brightness will depend upon
the roughness. Take a look at some of the radar
images of rivers to see what wet areas look like

It's not the tornado that is the concern. It is
the storm and mass of clouds and the convergience
of the two fronts that would be the object of
concern. Some of the storms go up miles into the
air thereby giving us such nice treats as
hailstones!

Controlling something like that is where the
problem lie. I've of ten thought about two planes
pulling a REALLY big ZIP-LOC bag and capture the
storm in it then another plane fly's by and closes
the Zipper and then........ Ain't gonna happen!
