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.)

粒子群算法源程序，是近年来发展起来的一种新的进化算法。有实现容易、精度高、收敛快等优点。是一种并行算法。(Particle swarm algorithm source code, is a new evolutionary algorithm developed in recent years. There are easy to implement, high precision, fast convergence and so on. Is a kind of parallel algorithms.)

雷达天线方向图仿真，非常简单实用。。。。。。。。。(Radar antenna pattern simulation, a very simple and practical)

We describe in this paper a new hybrid approach for mathematical function optimization combining Particle Swarm Optimization (PSO) and Genetic Algorithms (GAs) using Fuzzy Logic for parameter adaptation and integrate the results. The new evolutionary method combines the advantages of the fuzzy logic to give us an improved FPSO+FGA hybrid method. Fuzzy Logic is used to combine the results of the PSO and GA in the best way possible.
