摘要

摘要: 针对分布式MIMO雷达正交相位编码信号和其失配滤波器组分开设计输出的距离旁瓣电平仍然过高的问题，该文提出一种正交相位编码信号和失配滤波器组联合设计方法。首先，以约束信噪比损失和最小化失配滤波组输出的距离旁瓣电平为目标，构建联合设计准则。然后，根据最小p范数算法的理论，给出一种基于L-BFGS算法的双最小p范数算法进行求解。仿真结果表明，与分开设计方法相比，该文方法输出的距离旁瓣电平可以进一步降低。

Abstract: For the high Range Sidelobe Level (RSL) of designing distributed MIMO radar orthogonal phase coded waveforms and its mismatched filter bank separately, a joint design method of Orthogonal Phase Coded Waveforms and Mismatched Filter Bank (OPCW-MFB) is proposed in this paper. Firstly, by controlling signal-to-noise ratio loss and minimizing the RSL of mismatched filter bank output, the joint design criterion is formulated. Then, based on the theory of a least-pth minimax algorithm, a double least-pth minimax algorithm with the L-BFGS as its sub-algorithm is proposed to solve it. Numerical results show that compared with the separate design methods of OPCW-MFB, the proposed method can further suppress the RSL.
