摘要：
Considering the platform with variable velocity, a 2-D frequency domain algorithm for SAR echo signal simulation is presented. Because it is difficult to obtain its two-dimensional frequency spectrum by use of a curvilinear trajectory with varying velocity, based on the geometric model of a side-looking SAR and reversion of series, the 2-D spectrum can be derived accurately. Moreover, the range-variant problem is analyzed and effectively solved by introducing a new compensation function. The results show that the efficiency of SAR echo signal simulation can be improved with high phase accuracy. Several simulation and processing results are presented to demonstrate the validity of the proposed algorithm.
