混沌背景下瞬态弱信号检测方法的研究

The Research of Weak Signal Detection Against the Chaotic Background

混沌背景中的微弱信号检测在通信、自动化等需实时处理领域中有很广阔的应用前景,也是目前的热点研究课题。利用背景信号为混沌信号这一先验知识,对基于混沌理论的混沌背景下弱信号检测的一般原理进行了研究,介绍了其近些年来的研究现状,分析了五种典型的混沌背景下瞬态弱信号检测的方法,并提出了今后进一步研究的方向。

The technology of weak signal detection against the chaotic background has potential applications in engineering demands of real time such as in communication and automation demands. The application has become one of important issues. Using chaotic signal as background signal , the paper studyed the conception of weak signal detection against the chaotic background and its basic structure based on chaotic theory. This paper also introduced its some overview in recent years and summarized five current algorithms. Finally aim to motivate the research works on this field are discussed.
