%X In this paper, an advanced method in precisely computing of yaw-angle in space-borne Synthetic Aperture Radar (SAR) system is proposed in detail. Standard elliptical orbit model as well as earth ellipsoid model is assumed in the course of development, thus the bias caused by conventional approximation is eliminated. The result of this paper is popular for different kind of space-borne SAR system. A simple algorithm suitable to fast computation for space-born SAR system is also exploited in this paper. The result of simulation in condition of TerraSAR-X system is given in the end. By using the computing method of this paper, emendation error after yaw-steering can be reduced to centesimal Hz level. Thus, precise computation of yaw-steering is successfully achieved.
