Analysis was performed on bistatic radar data taken at White Sands Missile Range WSMR in Support of the evaluation of Space Time Adaptive Processing STAP algorithms and the characterization and modeling of monostatic and bistatic scattering. The analysis was confined to data from the flat semi-desert valley floor. Two Sets of measurements were made, the first using the ground based RSTER antenna for reception in combination with ground based and airborne transmitters. The frequencies were at or near 435 MHz and included VV, VH, HV and HH polarization combinations. The second set of measurements used airborne platforms for both transmitting and receiving and were taken at 141MHz and 431 MHz for VV, VH and HH polarization combinations. The two sets covered different spans of grazing angles. The data were analyzed to determine the bistatic scattering coefficient of the terrain as a function of out of plane angle and grazing angle, and to interpret the results in terms of the Generalized Lambertian Formula.
