| Abstract: | Based on study of the location method of Range-Doppler information, an R-D location simulation model for pixels in spaceborne SAR imagery was proposed. By using this model, the whole SAR imaging process and pixels location were simulated. The validity of the location method was confirmed by computer simulation. The precision and the error of this method were analyzed. The simulation results accord with the theoretical analysis. |
