摘　　要：为了有效利用MIMO体制雷达的波形分集能力,需要对雷达发射波形进行正交性设计,从工程实现的角度出发,针对MIMO雷达发射信号的正交性要求,利用序列二次规划方法设计正交相位编码信号波形。通过仿真分析,重点研究了信号数量、码长对波形正交性能的影响以及波形与雷达发射方向图之间的关系,验证了该方法的有效性和优异性,并与经典的遗传算法进行了仿真比较,最后依托波形产生系统完成了波形的工程实现,并且成功应用到了雷达系统中。结果表明,采用该方法能够获得较低的自相关旁瓣峰值和互相关峰值,设计出符合雷达系统要求的正交波形。To effectively utilize the waveform diversity ability of MIMO radar,the orthogonality design of radar transmitted waveform is critical. From the perspective of engineering implementation and based on the orthogonality requirements of the MIMO radar signal,this paper designs orthogonal phase coded signal waveform by using the sequential quadratic programming method. Simulation mainly studies the influence of the signal number,code length on the performance of the orthogonal waveform and the relationship between waveform and transmit beam pattern with radar,the validation of the proposed method is effective and excellent,and simulation comparison with classical genetic algorithm is also presented to show its superior. Finally,based on the waveform generation system,this paper completes the engineering implementation of the waveform and apply it into the radar system. The simulation results show that this method can get low autocorrelation and crosscorrelation,as well as design the waveform that meets the requirements of radar system.
