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.-
