Development of a new multiband UWB radar for object-sensing is described. The radar transmits pulses with duration varying from 450 to 1170 ps and peak power from 200 to 400 mW and detects signals with a conversion gain of 6.5-9.5 dB over a 5.5-GHz bandwidth. It has a range resolution of around 1 inch. The radar performs well through tests of various samples, demonstrating its success for sensing objects. The multi-pulse/multi-band feature allows the radar to achieve both fine range resolution and long operating range, and enhanced target detection and classification. © 2007 IEEE.
