Investigation of localization accuracy for UWB radar operating in complex environment

Abstract

The aim of this paper is to investigate localization accuracy of ultra wideband (UWB) radar with a minimal antenna array taking in the account complexity of the real environment (extended and multiple targets, presence of wall or other obstacle in the line of sight, practical restrictions of antenna setting). Simulation-based results show how the localization accuracy depends on the radar range resolution, deployment of the radar antennas and the accuracy of ranges estimated between transmitting antenna-target-receiving antenna. As the output, the distributions of the average localization errors in the monitored area are obtained. Their correctness is demonstrated by processing of the signals acquired by two M-sequence UWB radars with different range resolution and coverage.
