摘　　要：分析脉冲串信号的两种匹配滤波器—梳状滤波器和窄带滤波器实现脉冲串匹配滤波的原理。提出一种新的脉冲串匹配滤波方法,即通过频谱取样实现脉冲串的匹配滤波。理论分析和仿真结果证明,该方法能很好的滤除信号中的噪声。The principle of comb filter and narrowband filter to realize matched filtering of pulse train is analyzed. A novel matched filtering method of pulse train using spectrum sampling to realize matched filtering is proposed. The theoretical analysis and simulation show that the method is effective and can perfectly remove the noise in pulse train signal.
