A Multifrequency Radar System for Detecting Humans and Characterizing Human Activities for Short-Range Through-Wall and Long-Range Foliage Penetration Applications
Figure 16
Detection of a human target placed 4 feet behind a 10.4 inch thick brick wall. Both no target and target present cases are shown, as well as the implementation of the background subtraction algorithm which suppresses non-target responses and enhances target response.
