Research Status and Prospect of InSAR Performance Evaluation Methods

Interferometric Synthetic Aperture Radar (InSAR) is a technique used in geodesy and remote sensing by interferometric method. The system parameters, error indicators and processing algorithms of InSAR directly influence its application value. In this paper, the processing flow of InSAR is introduced, and the existing evaluation methods in each step are systematically summarized. Then the advantages and disadvantages of each method are analyzed. In view of the development of InSAR, the research trend of performance evaluation is prospected.
