Abstract
This invention relates to sense through the wall radar. A main channel of a radar system () is operated at a frequency capable of penetrating opaque barriers such as the wall () of a building () to sense targets () therein. The main channel performance may be impaired by multipath interference, i.e., radar returns resulting from targets () outside the building () illuminated by reflection from the wall (). A guard channel of the radar, operating at a higher frequency which does not penetrate the wall (), is used to identify targets () outside the building () and suppress the multipath interference they produce in the main channel.
