Application status and prospect of InSAR technology in power engineering

In recent years, space-borne InSAR technology has rapidly become one of the commonly used new surveying and mapping technologies due to its advantages, such as all-time, all-weather, spatial continuity, high precision and non-contact. Firstly， this paper introduces the basic principles and application fields of InSAR technology; then analyzes the application advantages of InSAR technology in power engineering; summarizes the current application of InSAR technology in power engineering,and looks forward to the prospect of the popularization and application of InSAR technology in China's power engineering industry.
