Verification and analysis of ground-based synthetic aperture radar monitoring accuracy based on controllable strong scattering targets
Synthetic aperture radar can realize continuous deformation monitoring with high precision in the monitoring area,which is of great significance in the field of mine safety production and landslide geological disaster rescue.In order to study its deformation monitoring ability and accuracy,a set of high-precision control-lable high-scattering target Angle reflector calibration device was adopted as the verification target,which was deployed on the remote real slope of a metal open-pit mine.The whole displacement process was monitored by S-SAR slope radar monitoring system developed by China Academy of Safety Science and Technology.The results of radar deformation monitoring were analyzed and compared with those of high-precision device.The experimental results show that,in the remote monitoring scenario of metal open-pit mine,the displacement and deformation trend obtained by S-SAR slope radar monitoring system is consistent with the actual monitoring target displacement trend,and the mean error is within 0.1mm,which effectively verifies the feasibility of the system for slope deforma-tion monitoring and the sub-millimeter monitoring accuracy.
