| 摘 要： | 针对双基地SAR距离徙动受发射和接收二维距离变化影响的问题，提出了一种提取平移不变模式双基地SAR频率变标因子的新方法。该方法将距离徙动随二维距离的变化转化为随一维距离量的变化，然后通过合理的线性近似得到了不受距离参数影响的变标因子；在此基础上，将线性频率变标算法推广到了双基地SAR领域；最后通过仿真验证了该算法的有效性。

| Abstract: | A new approach to the range-independence frequency scaling (FS) factor of translational invariant bistatic synthetic aperture radar (SAR) is presented to solve the problem that the range cell movement (RCM) of bistatic SAR is influenced by transmitter and receiver range histories. The change of the RCM with two dimensional ranges is translated into that with one dimensional range, so the independent FS factor is acquired with the linear approximation of range migration. And based on this new approach, the FS algorithm is extended into translational invariant bistatic SAR. Finally, the new approach is validated by point target simulations. |
