UWB radar and leaky waveguide for fall on track object 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 slotted waveguide transmission line. A rectangular section, slotted waveguide is maintained all along the railway platform and used as a succession of monostatic radars. A design procedure is described. A procedure of extraction of target's electromagnetic signatures is discussed; simulation results are produced.
