Surveillance for 1000 kV transmission tower deformation using high-resolution SAR satellite

Under the conditions of present situation and requirements of wide area surveillance for UHV transmission line and tower in natural disaster weather, the technology of using high-resolution SAR satellite to detect UHV transmission line and tower deformation was discussed. Firstly, the fundamental characteristics of SAR image were analyzed. And the target characteristics and target recognition technology of UHV transmission tower in high-resolution SAR images were studied. The algorithm of peak characteristics detection was adopted to recognize the UHV tower targets in Wuhan UHV AC test base. Then, the test of UHV transmission tower deformation was processed. The experimental results show that using SAR target recognition technology can extract the main structure of UHV transmission tower, and the method of using high-resolution SAR images to identify the deformation of UHV transmission tower is feasible.
