UWB radar for ground vehicle self protect

The authors describe the concept of using an impulse ultrawide-band (UWB) radar system to detect, acquire, identify and track incoming armor-piercing rounds which threaten a ground vehicle. Data illustrating the ability of a prototype impulse radar to discriminate between different target shapes are presented. The sensitivity of the CFAR (constant-false-alarm-rate) receiver used with the system appears to be adequate, but ground clutter poses a serious problem. Techniques for discriminating against ground clutter are being explored.<>
