Geological disaster monitoring technology along transmission line based on InSAR

Transmission lines are widely distributed in mountainous areas, hills and other areas, and geological subsidence caused by natural disasters or man-made destruction poses a great threat to the safety of transmission line towers. In order to realize accurate and efficient monitoring of geological hazards along the transmission line, this paper analyzes the technical principle of InSAR (Interferometric Synthetic Aperture Radar), and puts forward a complete monitoring process based on the characteristics of the transmission line. Using the above method to analyze satellite data for 17 consecutive months along a certain line, 105 hidden danger points were identified through analysis. After on-site verification, the geological subsidence of the hidden danger points is true, which provides a new way for the monitoring of geological disasters along the transmission line.
