一种低信噪比背景下脉冲参数提取方法

Pulse Parameters Analysis in Low SNR

通过对单频采样信号的分析 ,应用匹配滤波原理在白噪声背景下最大限度提高信噪比 ,并构造了信号跳变沿定位的判别准则 ,给出在低信噪比的条件下提取脉冲信号的重复周期。

This paper discusses an algorithm to increase SNR with the theory of matched filtering in the white noise based on analysis of signals of single frequency, and constructs a rule for decision of pulse orientation. It then brings forward an algorithm which can extract the parameters of the pulse signals in lower SNR such as pulse repetition time and pulse width.
