摘要
轨道地表穿透合成孔径雷达(GPSAR)是为了评估UWB SAR在地雷目标探测中的可行性和效能,而用高于地面数米支架作为轨道构建的一个地雷目标探测系统。文中首先介绍了轨道GPSAR的系统框架,接着介绍了该系统在射频/耦合抑制、近场SAR成像,以及埋设地雷目标检测方面所作的工作,最后,用一系列实测试验数据及其处理结果验证了轨道GPSAR检测地雷目标的性能。
A standoff landmine detection system, Rail-GPSAR, was built for the purposes to evaluate feasibility and effectiveness of landmine detection using UWB SAR. The system architecture of Rail-GPSAR is introduced firstly, and then some new approaches to Radio Frequency Interference （ RFI ）/coupling suppression; near - field SAR imaging and detection of the buried landmines are proposed. Finally the detection performance of Rail-GPSAR is validated by a series of field experiments.
