A question regarding in-space synthetic aptitude radar - I have seen different spacecrafts working on different wavelengths, from the longer wavelength L-band (which is where ALOS-2 will work, as is the Argentine SAOCOM-1A/B and the very first civilian SAR satellite, SeaSat 1), C-band (Sentinel-1, RADARSAT-1/2 etc.), S-band (Chinese HJ-1C, Russian Condor) to shorter wavelengths at X-band (TerraSAR-X/TanDEM-X, COSMO-SkyMed etc.). What are the advantages and disadvantages of operating radars from space in each of these wavelengths?  :-\

Excerpt from Q and A in Y-1 breafing

JAXA said ESA and Canada's rader is long history in C-band and see sea etc.Itary and Germany's rader see city etc in X-band.Japan started from earth resorces satellite,so L-band rader see crustal movements.It is suitable for quake-prone Japan.

First Go/No Go Decision -'Go'
May 23, 2014 19:35 JST

This is an updated launch countdown report on the Advanced Land Observing Satellite-2 "DAICHI-2" (ALOS-2) which will be launched using the H-IIA No. 24 Launch Vehicle (H-IIA F24). After the weather conditions checked out, the green light has been given for H-IIA F24 carrying "DAICHI-2" to leave the Vehicle Assembly Building for the launch pad. The scheduled launch time is May. 24, 2014 12:05:14 JST.

What are the advantages and disadvantages of operating radars from space in each of these wavelengths?  :-\
I don't know the specifics. But shorter wavelengths have better resolution (anything shorter than a wavelength is, effectively, invisible to said wave). Also, different wavelength have different behaviors wrt humidity, soil penetration, tree coverage, etc. For example, if you can use an image that penetrates three and another that doesn't, you can get a much better estimation of forest resources. If your band penetrates soils but is sensible to water, using a topographic map you can know humidity.
Longer wavelengths, since have less resolution can do wider swaths with same complexity. And once you get into polarized beams, certain thing reflect polarized radio differently.
I know that CONAE has stated many times that L-Band was clearly a civil radar and lacked any use for military applications, due to its low resolution.
