圆弧式合成孔径雷达的精度测试试验

Accuracy test of a circular arc SAR

针对地质灾害传统监测手段需在监测面布设设备,且不能弥补全面监测的缺陷。圆弧式合成孔径雷达具有监测面广、监测频率高、监测精度高、耐候性好等优点,是一种更能满足地质灾害全面在线监测的可靠设备。为确认该设备的具体效果和精度,采用一种带千分尺的可移动角反射器对一款圆弧式合成孔径雷达进行了测试。测试结果表明该款雷达在恶劣天气环境下能实现全面域的地质灾害监测,且监测频次高、监测精度高,是一个更加全面有效的地质灾害在线监测手段。

In view of the defects that the traditional monitoring methods of geological disasters need to deploy equipment on the monitoring surface and can not realize comprehensive monitoring.Arc SAR has the advantages of wide monitoring area,high monitoring frequency,high monitoring accuracy and good weather resistance.It is a reliable equipment that can better meet the comprehensive on-line monitoring of geological disasters.In order to confirm the specific effect and accuracy of the equipment,a movable angle reflector with micrometer is used to test a circular arc SAR.The test results show that the radar can realize comprehensive geological disaster monitoring in bad weather environment,with high monitoring frequency and high monitoring accuracy.It is a more comprehensive and effective online geological disaster monitoring means.
