UWB Radar for Railway Fall on Track Object Detection and Identification

This paper presents a new system for detecting and identifying objects fallen onto railway tracks. The proposed solution is based on an ultra-wideband (UWB) radar technique combined with a long travelling wave radiating microwave transmission line. This line is maintained adequately all along the railway station platform. Scheduled steps for system realization are presented. A preliminary analysis of different transmission lines which could be used and their performance is provided. Automatic Target Recognition (ATR) application, which describes identification procedure, is discussed. An overview of extraction methods is provided and a procedure of selection of contributing poles is presented. Available target identification techniques based on UWB pulse are analyzed and compared to experimental results.
