| 摘 要： | 针对机载海洋激光探测系统接收信号噪声的非平稳性及与信号的相关性问题，文中利用局部相关特性建立了一种广义空间相关模型，把与信号相关的噪声转化为独立于信号的加性噪声，提出了一种基于背景分析的三重相关检测弱小信号的方法，实验结果表明该方法是一种抗噪性能强，自适应性能好的弱信号检测方法。

| Abstract: | To solve the problem of noise nonstationarity
and signal correlation in the signal information received by airborne oceanic laser
detection system, a generalized space correlation model is founded in the article so as to
convert the noise correlated with signal to additive noise independent from signal, using
local correlation properties. A triple correlation method for weak signal detection based
on background analysis, is also presented in this paper. The results of experiments show
that this method is a good one for the weak signal detection, which with nice combat noise
performance and adaptivity. |
