| Abstract: | The reconnaissance of SAR（synthetic aperture radar） satellite can support the electronic war of SAR strongly.A model of reconnaissance under the background of that the ground-based receiver tracking and reconnoitering the SAR satellite is established.Real antenna parameters and orbit parameters are used in the model.Based on the scene model,the antenna gain in azimuth of different kinds of operating modes are obtained,and with the use of interpolation the antenna gain in range is obtained.With the simulation analysis of reconnaissance signal of SAR satellite,it orders the foundation for study on parameter estimation and operating modes recognition. |
