Bistatic Synthetic Aperture Radar Point Spread Function Characteristic Analysis

Based on the point spread function (PSF) theory, the side-lobe extension direction of the impulse response in bistatic synthetic aperture radar (BSAR) is analyzed in detail; in addition, the corresponding auto-focus in BSAR should be considered along iso-range direction, not the traditional azimuth resolution (AR) direction. The conclusion is verified by the computer simulation.
