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。(Beamforming based on range-angle decoupling of MIMO-OFDM radar. the definition of MIMO-OFDM radar and OFDM-MIMO radar in different journal are different. the MIMO-OFDM radar is equal to IET journal, that is transmitting end is frequency diverse array. Using frequency diversity improve target detective performance, but beanpattern is range-angle coupling, which have an effect on beamforming.)
