| Abstract: | By using the ephemeris data of space-borne SAR image,a system geometric correction algorithm for range-Doppler model was investigated.A new fast system geometric correction algorithm based on classifying-grid was proposed.Furthermore,a certain area's image from domestic satellite is located by using this algorithm.It proves the correctness of the algorithm.And this algorithm can be applied to the automatic target location without control point in the precise attack. |
