A location method without reference points for air-borne SAR image is proposed. This method exploits related parameters in auxiliary data of SAR image, based on geographic coordinates of a point and the correlation of range-azimuth between this point to another point in the geodetic coordinate system, convert the problem of SAR image location to solution of geodetic problem. The effects on location precision caused by system error are studied. The experimental results on real-world SAR image validate effectiveness of the proposed method.
