Improved Identification of Underground Targets Using Video-Pulse Radars by Elimination of Undesired Natural Resonances.
Abstract
A process for identifying and determining the structure, depth and relative position of an underground tunnel from its backscattered response is presented. Application to theoretical and measured tunnel echoes is included with very satisfactory results. Basically, the process involves the isolation of a clutter free tunnel response by effectively removing all undesired poles and clutter or noise from the original (unprocessed) echo. The results can be evaluated by Grey-Level Mapping a traverse of responses over the tunnel. The employed signal-processing techniques are very general and can be used for detection of other subsurface targets. (Author)
