The Research on echo signal processing for outdoor RCS measurement system

In view of the demand for full size large stealth target's RCS measurement, the outdoor field RCS measurement, especially the direct signal processing technology, is also put forward higher requirements. In offsite relative calibration, the calibrator can be exactly equal to the reference branch coherent measurement system and how to make use of this characteristic will directly affect the precision of RCS Calibration. In this paper, how to improve the accuracy of RCS. Measurement by using more echo signal energy is also studied, and the processing method is simulated and proved to be correct.
