本文作者开发基于E5071B型矢量网络分析仪(VNA)的高分辨率探地雷达系统(LANRCS-GPR),该系统立足于频率域探地雷达系统的宽频带和适应性强的优点之上,充分发挥了矢量网络分析仪具有的超宽带、高精度测量等特性.该系统采用LAN方式进行系统联机控制方式,使系统组建成本低廉、易于扩展;本系统采用了计算效率高的F-K偏移方法作为实时成像方法.系统测试实验表明,该系统具有很高的探测分辨率,探测精度高,信号信噪比高,系统动态范围大,而且系统的操作灵活可靠,适应范围广,系统功能可扩展性强.该系统的研究开发为将来成品频域探地雷达系统的研发提供了理论、实验基础,同时也为电磁波传播研究及电磁探测研究搭建了一个采集数据精度高、信息量大、适应范围广、操作方便的实验平台.
