摘要 本文详细研究了双基地合成孔径雷达的等效单基地成像模型,在此基础上提出了一种适用于双基地SAR的扩展ETF(Exact Transfer Function)成像算法.在原有单基地ETF算法的基础上,新算法采用由双基地成像几何关系所确定出的新的方位聚焦相位函数,算法的计算流程及效率和单基地SAR的ETF成像算法相同,优点是不需要任何的插值计算,论文同时讨论了算法的适用条件.最后通过点目标仿真验证了算法的有效性. The monostatic equivalent geometry model of bistatic synthetic aperture radar （SAR） is discussed and an extended ETF imaging algorithm for bistatic SAR is proposed. Compared with the conventional monostatic ETF algorithm, the azimuth focusing phase functions, calculated with the parameters of bistafic imaging geometry, are adopted in this algorithm. The procedures and efficiency of this approach are the same as the ETF algorithm for the monostatic SAR and without any interpolations. The limitation of the proposed approach is also discussed. The algorithm was validated through point target simulations.
