Positioning of moving non-line-of-sight targets behind a corner

A stand-off radar system with the capability of “seeing” behind corners would be of great importance for civilian surveillance purposes, for automotive radar, or in urban warfare. Detecting moving people and objects in the shadow region of a street corner by exploiting multi-path propagation of radar waves has previously been demonstrated in experimental set-ups. To position the detected targets, a scanning, narrow beam radar system is suggested. Simulations are used to investigate the performance of the system. Targets are found to be positioned with a good accuracy when the geometry of the scene is known. If errors are introduced in the assumed geometry, the obtained positions are still centered on the true tracks.
