Abstract：In this paper, the satellite SAR imagery is regarded as an image which is acquired from the frame projection sensor approximately based on photogrametry theory. The satellite SAR collinearity equation is revised and a new location model is proposed. As an example, the RadarSat Imagery is tested. Experiment result demonstrates the new model formulation is simple and the resolution is stable without any orbit ephemeris and imaging parameters, and also location accuracy reaches pixels.
