Automatic Through the Wall Detection of Moving Targets using Low- Frequency Ultra-Wideband Radar

摘要

This paper presents a time-domain, Moving Target Indication (MTI) processing formulation for detecting slowmoving personnel behind walls. The proposed time-domain MTI processing formulation consists of change detection and automatic target recognition algorithms. We demonstrate the effectiveness of the MTI processing formulation using data collected by an impulse-based, low- frequency, ultra-wideband radar. In this paper, we describe our radar system and algorithms used for the automatic detection of moving personnel. We also analyze the false alarm and detection rate of four operational scenarios of personnel walking inside wood and cinderblock buildings.
