摘　　要：综合射频技术的发展为雷达、电子战一体化提供了硬件平台,下一步的发展将是雷达和电子战信号共享。随机跳频干扰频谱具有不规则性,可作为一种低截获的雷达信号,但同时也会导致脉冲压缩后旁瓣过高。直接运用谱修正算法处理虽然可以有效抑制旁瓣,但也造成较大的信噪比损失,而且还存在稳健性差的问题。通过在谱修正算法中加入调整因子,可以折中选择主旁瓣比和信噪比,同时可以改善算法的稳健性。The development of integrated radio frequency （RF） technology provides a hardware platform for the integration of radar and electronic warfare.The next step will be the sharing of ra dar and electronic warfare signals. Random frequency hopping jamming, with irregular spectrum, can be used as a radar signal of low interception, but at the same time will lead to high sidelobes af ter pulse compression.Although spectrum correction algorithm can directly suppress sidelobe effec tively,it causes a large loss of signal to noise ratio,and there is still a problem of poor robustness. By adding an adjustment factor to the spectrum correction algorithm, main to side lobe ratio and signal to noise ratio can be compromised, and the robustness of the algorithm can be improved.
