An MHT algorithm for UWB radar-based multipleudhuman target tracking

摘要

This paper presents a multiple hypothesis trackingud(MHT) framework for tracking the ranges and velocities ofuda variable number of moving human targets via a monostaticudultra-wideband (UWB) radar. The multi-target trackingud(MTT) problem for UWB radar-based human target trackinguddiffers from traditional applications because of the multitude ofudobservations (multipath scattering) per target in each scan, dueudto the short spatial extent of the transmitted UWB signal pulseudwidth. We develop an MHT framework for UWB radar-basedudmultiple human target tracking that extends a previously studiedudhuman tracking algorithm. We present experimental results inudwhich a monostatic UWB radar tracks both individual andudmultiple human targets, even with changing numbers of targetsudacross radar scans.
