Through-the-wall differential radar

Abstract
We have designed and built an ultra-wideband differential radar that images targets moving behind walls, fences, trees, and other obstacles. We have demonstrated the differential-radar concept in anechoic, indoor, and outdoor environments. The outdoor demonstration proved the radar's ability to detect people moving behind walls and illustrated its capability for suppressing high-level clutter from the radar imagery.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.
