Experimental results describing the performance of an active phase-switched screen (PSS) radar absorber operating against modulated microwave signals are presented. A planar PSS is illuminated by pulse modulated and FM modulated radar signals with a carrier frequency of 11 GHz. The measured frequency spectrum of the reflected signals from the PSS in both its active and passive states are presented and compared to theoretical predictions.
