Abstract

For the application of high-resolution airborne SAR stereo positioning, a kind of approximately precise parameter error model has been adopted in this paper to discuss the influence of the direct or indirect-inputted parameters' errors on the final stereo positioning accuracy. Through the describing of the precise parameter error model and the analysis about the error sources for the airborne SAR stereo positioning model, the corresponding simulation tests have been taken in the test site, and the results have shown that most of the direct-inputted parameter errors have little influence on the final plane stereo positioning accuracy, while almost all of the them will introduce more error into the elevation computation. And the indirect-inputted phase error arisen from time delay is the main error source during the process of atmosphere transmitting of radar wave.
