| Abstract: | This paper theoretically presents the geocoding principle and method for airborne SAR system image, which is converted only by the positional and directional data from the aircraft mounted SAR. The calculated equations and error functions of the geocoding SAR system are derived and the differences of the geocoding SAR image converted by INS data, GPS data or INS/GPS combined data are also analyzed. Besides, the simulated results are suggested in this paper. |
