摘　　要：阐述了无法获得双基地SAR二维频谱解析解的原因,针对该问题采用泰勒级数展开的方法得到了近似距离方程。然后,在近似距离方程的基础上推导出二维频谱模型的解析表达式。最后,通过仿真给出了模型的精度,验证了模型合理性。The reason why it is impossible to obtain analytical solution of bistatic SAR frequency spectrum is given,and an approximate range equation is presented by taylor series expansion. Then,the bistatic SAR frequency spectrum model based on approximate range equation is given. Finally,the accuracy and rationality of model is performed by simulation.
