Abstract

The objective of the present investigation is to use radar data to detect targets situated on or under a road surface, and, at the same time, minimize the number of false alarms. The data used here have been collected by the Army Research Laboratory (ARL) Synchronous Impulse Reconstruction (SIRE) Radar. These data have been processed at different ranges from the radar, at different depression angles, and with different resolution. This has been achieved by integrating the data collected during the forward motion of the radar along the road. As a result, it has been possible to produce a series of images of the road in front of the radar at progressively better resolution. We show how the exploitation of the different behavior of clutter and targets at different resolution allows higher rates of target detection at lower false alarm rate than otherwise possible.
