Summary:Spaceborne Radar plays an essential role in the military. In hostile situations, synthetic aperture radar (SAR) is subject to deliberate interference by people. In this paper, we introduce narrowband interference and wideband interference and analyze their principles. Aiming at the problem of eliminating narrowband interference, the Least Mean Square (LMS) algorithm is implemented in this paper, and its applicability is verified by signal simulation. The simulation results show that the LMS method has a good suppression effect on narrowband interference. This method can restore the actual scene image without destroying the original spectrum. In this paper, anti-jamming technology is studied, which is of great significance to ensure the information acquisition ability of the spaceborne SAR system.
