摘　　要：文中利用信号相位匹配原理,在背景噪声谱幅度已知的条件下,结合低截获雷达信号的特点,提出了一种全新的微弱信号提取法,即基于单点阵的分段信号相位匹配法。通过仿真实验表明,该方法对强白噪声或强相干干扰环境下低截获雷达信号的提取具有很好的效果。Based on the signal phase matching principle, a new extraction method called subsection signals phase matching of single antenna has been proposed in this paper when the amplitude of background noise spectrum is known. The experimental results shows that this method can extract the useful signal effectively under white noise or coherent interference.
