An EMD Based Sense-Through-Foliage Target Detection UWB Radar Sensor Networks

In this paper, we propose an empirical mode decomposition (EMD)-based approach to ultra wide band radar for sense-through-foliage target detection. When the radar signal quality is good, the EMD-based target detection approach performs well by comparing to the no target case. When the radar signal quality is poor and a single radar echo fails to detect the target, we first apply Rake structure in radar sensor networks to combine radar echoes from different radar cluster-members and then the EMD-based method could successfully carry out the target detection.
