Inflight measurement of antenna pattern is a key technology of spaceborne SAR calibration.This paper describes a new method of antenna reception pattern measurement for spaceborne SAR using encoding transmitters.Considering the characters of the SAR system,the principle is described briefly.The orthogonal modulation code is chosen and the arithmetic of generating,receiving,decoupling and processing signals is derived.The results of computer simulation prove that this measurement method is feasible.
