This paper presents a method by jointly designing the transmitted waveform and mismatched filter to suppress the pulse compression sidelobe level
thereby improving the detection and imaging performance of weak target. A waveform and mismatched filter joint design algorithm is proposed based on block-coordinate-descent optimization framework. Simulation results show that the proposed method improves the pulse compression sidelobe performance with slight loss in the processing gain
and outperforms the conventional joint design method in terms of running time. Besides
the design scheme is extended to orthogonal waveform set and mismatched filter bank design
and a joint design method is proposed based on parallel optimization. The designed waveform set and mismatch filters show good orthogonality performance.
