Forward-looking mine detection using an ultrawideband radar

In this paper, we investigate the feasibility and effectiveness of using forward-imaging ultra-wideband radar technology for vehicular-based mine detection. A synthetic aperture is formed by moving the radar form side to side while the vehicle moves forward. In addition, the changing depression angle to the image area from the forward motion of the radar allows for depth resolution. Consequently, we generate 3D images of buried mines using a back propagation approach and a method-of-moments technique to model the backscatter from buried M20 mines. We developed software to simulate different imaging scenarios in order to define system limitations and optimize parameter values. For example, we generate imagery using different radar paths, and determine the effects of side-to-side sweep rate and vehicle speed on 3D resolution and overall system performance. Simulation results will be presented along with system design recommendations.
