多发多收合成孔径雷达（MIMO SAR）是近年来发展起来的一种新型雷达体制。与传统 SAR 相比，MIMO SAR 综合利用了波形分集和空间分集优势，如何衡量系统的分辨特性以及模糊特性成为亟待解决的问题。本文将模糊函数概念推广到 MIMO SAR 性能分析中，通过数学推导获得了广义模糊函数的解析表示，结果表明 MIMO SAR 系统分辨率不仅取决于发射波形参数以及合成孔径长度，还与发射波形集的正交性以及收发天线阵列流形密切相关，仿真实验验证了系统模型的有效性和相应分析的正确性。

In recent years,a new SAR concept based on Multi-Input Multi-Output (MIMO)configuration has drawn much attention.Firstly, a review was made about the development in the field under discussion.Then,the generalized ambiguity function of the conventional SAR into MIMO SAR case was extended.Next,a detailed analysis shows that the resolution of MIMO SAR not only depends on the parameters of the waveform and synthetic aperture length,but also depends on the array geometry of the multiple transmitters and multiple receivers.Simulations with a variety of parameter combinations demonstrate the derivation and analysis.
