Range-Doppler processing for indoor human tracking by multistatic ultra-wideband radar

Indoor measurements were performed to examine the feasibility of using range-Doppler processing for human motion detection in a highly cluttered environment by the multistatic ultra-wideband (UWB) radar. A novel hypothesis-testing based range migration compensation algorithm, which is especially suited to UWB radars, is proposed to increase the coherent processing interval for range-Doppler processing. For each receiver, the multistatic UWB radar provides a video sequence constructed by high-resolution range-Doppler images of a human target, which is promising for the analysis of human target characteristics.
