An MHT algorithm for UWB radar-based multiple human target tracking

Abstract

This paper presents a multiple hypothesis tracking (MHT) framework for tracking the ranges and velocities of a variable number of moving human targets via a mono-static ultra-wideband (UWB) radar. The multi-target tracking (MTT) problem for UWB radar-based human target tracking differs from traditional applications because of the multitude of observations (multipath scattering) per target in each scan, due to the short spatial extent of the transmitted UWB signal pulse width. We develop an MHT framework for UWB radar-based multiple human target tracking that extends a previously studied human tracking algorithm. We present experimental results in which a monostatic UWB radar tracks both individual and multiple human targets, even with changing numbers of targets across radar scans.
