The Reaserch of Weak Signal Detection based on Cross-orrelation and Chaos Theory

Nie Chunyan 2 Shi Yaowu 1 (Changchun Univ., Changchun 130012, China) 2 (Information Engineering Institute, Jilin Univ., Changchun 130025)  
In this paper, the principle of cross correlation detection and chaos theory are introduced .On this basis, a new method of weak signal detection based on combining cross correlation function with chaos theory .At the same time, simulation model, frame diagram and simulation results are given .The experiment results show this is a time domain signal processing method which has a lower signal to noise ratio limit .Therefore, it will has very good future in applications.
