Short-Range Tracking of Moving Targets by a Handheld UWB Radar System

8.1 Introduction

Ultra-wideband (UWB) radar systems have a variety of potential applications including through wall and through fire detection and tracking of moving targets during security operations, protection of reservoirs, power plants and other critical infrastructures against a terrorist attack, detection of trapped people after an avalanche or earthquake, and so on. UWB radar emissions applied for these scenarios are at a relatively low frequency (typically between 100 MHz and 5 GHz). Additionally, the fractional bandwidth of the signal emitted by UWB radar is very large. The result is a UWB radar system with a fine resolution that also has the ability to penetrate many common materials. Then, such systems are able to detect a moving person by measuring changes in the impulse response of the environments [1]. In the above outlined applications, a short-range UWB radar (range up to 20–25 m) is usually applied. Therefore ...
