摘要 以最小化峰值相关旁瓣为优化准则,采用约束非线性规划设计多输入多输出雷达的正交波形。所设计的正交波形采用相位编码信号,信号幅度恒定,相位取值任意。数值仿真实验表明,与本文所提到的以最小化积分相关旁瓣为优化准则的方法相比,所设计的信号自身具有更低的自相关峰值旁瓣电平,信号两两之间具有更低的峰值互相关电平。此外,还通过数值实验研究了自相关峰值旁瓣电平和峰值互相关电平与正交波形的信号数目和码长的关系。 A constrained nonlinear programming method is proposed for designing orthogonal waveforms applied to multiple input multiple output(MIMO) radar systems.The designed orthogonal waveforms are phase-coded signals with a uniform amplitude and arbitrary phases.The optimal orthogonal waveforms have lower auto-correlation peak sidelobe levels(APSL) and lower peak cross-correlation levels(PCCL),compared with those of other methods.Addationally,the relationships among APSL,PCCL and the size of the orthogonal waveforms are studied via numerical experiments.
