Due to the high sensitivity of the IR-UWB radar, the wide diversity of scattered waveforms would bring false alarms. Clutter reduction serves a vital role in signal processing steps to obtain the signal reflected only from the target, while it may also eliminate significant information. In this...
Abstract:In the actual working situation of the through-wall-radar, clutter causes serious interference to the detection of moving targets behind the wall. The moving target detection principle of classical IR-UWB through-wall-radar is analyzed and reviewed. Its detection performance is investigated b...
