Radar measurements of moving objects around corners in a realistic scene

Abstract

The possibility of detecting moving people around the corner using multipath propagation of radar waves has previous been demonstrated in experimental set-ups. Here, we present measurements from a realistic scene using a radar system operating at X-band in a stepped-frequency mode. The moving objects include person(s), bicycle, and car(s). A semi-monostatic single receiver-transmitter radar system was used as a data collector. All detections were made by using Doppler filter processing. We can identify target returns after one and two wall reflections. Two persons moving in the scene can be separated, when allowed by the range resolution.
