　　鉴于MIMO雷达的频率分集作用使其具有更高分辨率和更大的自由度，从MIMO雷达信号模型出发，以DOA估计为目的，分析得出了MIMO雷达发射阵列阵元间距的最佳值。然后在给定阵元个数情况下，提出了一种基于拉格朗日乘数法的MIMO雷达天线设计方法。该方法根据多元函数最值理论得到了一组唯一的发射接收组合，给出了MIMO雷达阵列最优设计的解析解。最后通过仿真实验验证了该方法的正确性和有效性。

As the frequency diversity of MIMO radar allows the radar to have higher resolution and more freedom, by analyzing the signal model for MIMO radar, this paper obtains the optimal interval value between transmitting array elements of MIMO radar, for purpose of DOA estimation. And then, in the case of given the number of array elements, a sort of design scheme for MIMO radar antenna is presented based on Lagrange multiplier method, where a unique transceiver combination is achieved in terms of extreme theory of multivariate function , and the analytical solution of optimal design for MIMO radar array is given. Finally, the effectiveness of this proposed scheme is proved through simulation experiments.
