自适应脉冲压缩算法是一种有效的旁瓣抑制方法,有利于消除大目标对邻近弱小目标的湮没影响。该文提出了一种改进的自适应脉冲压缩算法,利用对角加载技术抑制噪声,改善信噪比,提高自适应脉冲压缩算法的旁瓣抑制能力。仿真结果表明了该方法的有效性,与现有的自适应脉冲压缩算法相比,该方法的旁瓣抑制效果得到很大的改善,且有更高的输出信噪比。

Adaptive pulse compression technique is an efficient technology to mitigate the effects of side-lobes.In this paper,a modified adaptive pulse compression algorithm is proposed,which utilizes diagonal loading technology to compress noise,improve signal-to-noise ratio,and enhance the capability of suppressing the side-lobes.The simulation results manifest that the modified adaptive pulse compression is superior to the conventional adaptive pulse compression algorithm.
