Experimental study of vegetation clatter tn VHF bistatic radar

The results of long-term clutter tests are presented for short-range ground-based bistatic radar sensor operating at different carrier frequencies in VHF and lower UHF bands. Measured clutter realizations are analyzed in time and spectral domains. Total clutter power is increased with wind speed and system carrier frequency increasing, but clutter dynamics in time (gust factor) and the shape of clutter power spectrum remain practically independent from wind and frequency. The results coincide well with known clutter measurement results obtained mostly by monostatic radars.
