Experimental analyses of mutual shadowing effect for multiple target tracking by UWB radar

Ultra wideband (UWB) radars have appeared as the suitable technology for detection and tracking of moving persons in critical situations and environments. The experimental results of handheld UWB radar application for multiple moving persons tracking have shown that for such scenarios the target located nearby the radar antennas is very often visible only. The other targets can be also detected but with less reliability than that of the target located the most closely to the radar antennas. In this paper, we will outline an origin of this effect as the impact of the mutual shadowing of targets at the multiple persons tracking scenario. This explanation will be confirmed by the experimental measurements.
