Effects of geometry on clutter characteristics of bistatic radars

This paper deals with the clutter characteristics of multichannel airborne radars. The analysis is performed using the clutter spectral center, which is a descriptive metric, in addition to commonly used measures such as Doppler-angle traces, iso-range, and iso-Doppler contours etc. The clutter characteristics of monostatic systems in the presence of crab angles and system errors are first examined. Then, the analysis of bistatic systems is focused on the effect of geometry on the clutter characteristics. Several interesting rules made from observation for the clutter characteristics with bistatic geometry are discussed.
