Abstract：Ultra Wide Band (UWB) radar technologies for short-range detecting human targets are widely used in some special situations. Through wall detecting multi-stationary human targets via UWB radar, it is shown that the target located nearby the radar antennas is very often visible. Because of the attenuation of electromagnetic wave energy and mutual positions of the targets and radar antennas, the other targets far from radar antennas could be detected with less reliability. A novel method based on entropy is proposed, calculating the signal frequency complexity of different distances to confirm the range of detecting targets. Experimental data demonstrate that the proposed algorithm can improve the accuracy of multi-target detection effectively, and make further effort to improve the bio-radar detection efficiency.
