摘　　要：多输入多输出(MIMO)雷达正交波形设计是MIMO雷达系统设计中的一个重要环节,正交波形既要求雷达波形信号之间低的互相关性,又要求雷达信号具有低的自相关函数旁瓣。针对这一特性提出了提高相位编码信号波形自相关函数性能的CAN算法,在CAN算法的基础上进一步研究后,提出了适用于优化MIMO雷达正交波形互相关特性的MultiCAN算法,并给出了算法仿真结果。The orthogonal waveform design of multi-input multi-output(MIMO)radar is an important part of MIMO radar system design.The orthogonal waveform requires not only low cross-correlation among radar waveform signals,but also low autocorrelation function sidelobe of the signals.Aiming at the characteristic,this paper proposes the CAN algorithm to improve the autocorrelation function performance of phase-coded signal waveform.After further research based on the CAN algorithm,the MultiCAN algorithm is proposed to optimize the cross correlation characteristics of MIMO radar orthogonal waveform,and the algorithm simulation results are given.
