摘　　要：针对实际应用中的未知微弱信号的检测,特别是完全被噪声淹没情况下微弱信号的检测问题进行了论证,根据白噪声零均值的特性,利用将信号按时间分段后延时累加的方法,介绍一种有效的检测方法。The problem of detecting the stochastic resonancefor weak signal from strong noise in practical application was studied. According to the characteristic of zero mean of noise, and using the method of adding the signal after delay, introduced a effectual method of detecting.

关 键 词：微弱信号检测 延时累加.
