基于距离角度解耦的MIMO-OFDM雷达波束形成及优化。首先，MIMO-OFDM雷达和OFDM-MIMO雷达的定义在不同的期刊是不同的。这里MIMO-OFDM雷达的定义同IET期刊(见参考文献)，即发射阵列应用频率分集。发射阵列使用频率分集能提高目标检测性能，但是发射波束具有距离角度耦合，波束形成需要解除距离角度耦合。以距离角度耦合效应为目标函数，使用遗传算法计算目标函数最小时的发射载频组合。
English Description：
MIMO-OFDM radar beamforming and Optimization Based on range angle decoupling. Firstly, the definitions of MIMO-OFDM radar and OFDM-MIMO radar are different in different journals. Here, the definition of MIMO-OFDM radar is the same as that of IET Journal (see reference), i.e. transmitting array applies frequency diversity. Frequency diversity can improve the performance of target detection, but the transmitting beam has range angle coupling, so the range angle coupling needs to be removed in beamforming. Taking the distance angle coupling effect as the objective function, the genetic algorithm is used to calculate the combination of transmit carrier frequencies with the minimum objective function
