Abstract:
1. A system for performing radar cross section measurements of a target, comprising a radar system; an antenna associated with the radar system to transmit signals and to receive reflected signals from the target and a clutter source; an EM tagging device locatable proximate to the clutter source to spectrally tag the clutter source by causing changes in an electromagnetic signal reflected by the clutter source when a predetermined radar signal transmitted by the radar system is incident on the target, the clutter source and the EM tagging device; a module associated with the radar system to identify a spectrally tagged component of reflected signals received by the radar system from the target, the clutter source and the EM tagging device, wherein the module monitors the spectrally tagged component of the reflected signals received by the radar system, compensates for variations in an un-tagged component of the reflected signals caused by the clutter source and EM tagging device, and subtracts contamination caused by the clutter source and EM tagging device and their interactions with the target, to provide a radar cross section of the target with reflected signals from the clutter source and EM tagging device and any electromagnetic interaction between the clutter source and the target removed; and an output device to present the radar cross section of the target with reflected signals from the clutter source and EM tagging device and any electromagnetic interaction between the clutter source and the target removed.
