摘　　要：波束综合特别是等效发射波束的形成技术，是MIMO雷达区别于其他体制雷达的主要技术特点。通过对波束综合技术的研究和仿真，分析了波束综合技术的本质及其意义。仿真结果表明：波束综合技术的本质是为了增强回波信号的信噪比，弥补由于MIMO雷达发射信号在空间不能形成窄波束而带来的部分威力损失。The techniques of beam synthesize especially the equivalent transmitted beam forming are the main characteristic of technique for MIMO radar compared to others radars system. The paper analyzed the essence and meaning of beam synthesize by research and simulation. Simulation results testify that the essence of beam synthesize enhanced SNR of echo signal and recuperated partial loss of capability for measuring distance, thanks to MIMO radars aren＇t able to form narrow beam pattern.
