Abstract:In the bistatic synthetic aperture radar (SAR), the comodulation effect induced by transmitting and receiving antennas to the image amplitude is the main factor affecting the radiometric accuracy. Therefore, the corresponding mechanism must be determined, and a correction method must be developed. However, there is no effective calibration target and method for measuring the bistatic SAR range round trip antenna pattern. In this letter, it is pointed out that the comodulation effect is not only related to the … Show more
