Effects of Interference on Synthetic Aperture Radar Measurements: An Illustrative Example

Synthetic aperture radar (SAR) is a very important instrument for active remote sensing. However, it is common to find that SAR echoes are often contaminated by electromagnetic interference, which is referred to as radio frequency interference (RFI). This paper analyzes the impact of interference on SAR image and its post products. Qualitative and quantitative analysis of the adverse impacts of RFI on the simulated are illustrated from two perspectives, i.e., evaluation of imaging quality and interpretation of scattering mechanisms.
