弱信号检测技术研究

本文对弱信号的定义和弱信号的应用范围进行了概述,综述了微弱信号检测理论研究和实际应用领域的发展情况,重点比较了目前在微弱信号检检测技术中应用的方法:相关检测、离散信号的统计处理,基于小波分析的微弱信号检测,基于混沌振子的微弱信号检测,最后总结各个方法的特点.

Study on the Weak Signal Detecfion Method

On the base of consulting massive materials,the paper first makes the elaboration to the research Background of current weak signal,then compares with the current applied method in the weak signal detection:Self-correlation detection technology,Discrete signal statistical disposition,weak signal detection based on wavelet transform,weak signal detection based on chaotic oscillator.Lastly,it presents the characteristics of each method.
