二维相干技术在微弱信号检测中的应用

Application of 2-D coherence technology in weak signal detection

相干技术是一种利用数学方法突出相邻道之间信号的相似性,进而达到检测微弱信号、反映异常特征的一项新技术.本文在对相干计算的数学模型实现方法进行探讨的基础上,开发了一套相干技术的应用软件,并对理论模型和实际模型进行处理,取得了显著的应用效果.通过理论模型及实际模型的试验说明该方法是一种行之有效的微弱信号检测方法.

Coherence technology is a kind of method which uses mathematic methods to highlight the similarity of the signal between two neighboring channels in order to detect weak signal and reflect unusual characteristics.The author developed a set of application software of coherence technology based on the discussion about the realizing method of the mathematic model.The tests on theoretic model and practical model,which have good application effect,show that this method is effective in weak signal detection.
