This paper discusses in detail the characteristics of the AIRSAR data acquired, and provides an initial quantitative assessment of the accuracy of the radar inversion algorithms under these vegetated conditions.
Recent advances in polarimetric SAR show promise for augmenting the capability of traditional interferometric SAR. In particular, a polarimetric topography technique provides useful slope information, and polarimetric interferometry may be used to decompose the response into vegetation and ground surface contributions.

This paper compares the performance of four bare surface radar soil moisture inversion algorithms in the presence of measurement errors. The particular errors considered include calibration errors, system thermal noise, local topography and vegetation cover.
The Shuttle Radar Topography Mission (SRTM) flown on the Space Shuttle Endeavor on Flight STS-99 will produce digital elevation data of the Earth's land mass between 60 degrees north latitude and 54 degrees south latitude.
Several existing and future Earth and planetary radard will have multipolarization cabability.
