Abstract
A system for performing radar cross section measurements of a target may include a radar system and 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 is 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 may identify a spectrally tagged component of reflected signals received by the radar system from the target, the clutter source and the EM tagging device. The module monitors the spectrally tagged component, 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 removed.
