Patrick explained everything clearly: ARTS has robust tools for simulating
profiling radars, but these are in the development version. I should note that
I owe the repository an example case for MCRadar, which I expect to submit soon.

The MC module is called MCRadar.
I am not sure about what you mean with "thermodynamic radiation", but
MCRadar is intended to mimic radar measurements, including multiple
scattering, attenuation and antenna pattern. So I am assume it returns
what you are looking for.
For more details contact: Adams, Ian <ian.s.ad...@nasa.gov>
The module restricted to single scattering is called iyActiveSingleScat.

This was in fact my thinking, but not clearly expressed in my email. Why
not start with light rain and compare to iyActiveSingleScat (as this
method is very fast), and if all OK continue with MCRadar and cases with
more strong scattering.
We have not made any extensive comparisons, but in the tests I have done
iyActiveSingleScat and MCRadar agree as long multiple scattering can be
ignored. It seems though that MCRadar has a bias just above the surface,
but not critical as this is inside the clutter zone.
Bye,
