Abstract: In this paper, the high distance dimension sidelobe problem of frequency-code joint agile radar signal is studied after pluse compression. The integral sidelobe based on ambiguity function is used as the quantitative indicator of waveform optimization. Furthermore, the expression of the frequency-code joint agile radar signal and the ambiguity function of signal are derived. Then the waveform optimization design model based on minimizing ISL is established, and the alternating direction method of multipliers is applied to solve this model. Finally, the simulation results demonstrate the outperformance of our proposed methods in minimizing distance dimension sidelobe after pluse compression. Meanwhile, the optimization effect and efficiency compared with genetic algorithm are further improved.
