| 摘 要： | 简述自相关检测的原理及混沌理论,在此基础上,提出将自相关检测与混沌理论相结合检测微弱周期脉冲信号的检测方法。仿真结果表明在相同系统实验背景下,相结合的检测方案优于不加自相关的检测方法。此方法是目前信噪比门限较低的时域信号处理方法,因而具有广泛的应用前景。

| Abstract: | This article has introduced the autocorrelation detection principle and the chaos theory.A new method of weak periodic pulse signal based on combining autocorrelation function with chaos theory was proposed.The simulation results indicate that the united detecting method surpasses the detecting method without the auto correlation under the same experimental background.This method is suitable for low signal-to-noise ratio threshold within time domain signal processing methods,thus has the widespread application prospect. |
