摘要
介绍了混沌系统检测弱信号方法,结合自相关方法和滤波方法得到了弱信号检测的新方法??联合检测方法,给出了该检测方法一般模型,定性分析了噪声和干扰对系统检测的影响,仿真实验说明了所给方法对弱信号非常敏感,检测性能比单纯混沌系统检测性能优越。
On the basis of introducing chaotic system for weak signal detection, a mixed measuring system is presented,which is gotten by combining auto-correlation and filter with the chaotic system. It＇s general measuring model is given. The influence of noise and jamming on the chaotic detection is analyzed. Simulation indicates that the mixed measuring stem is very sensitive to weak signals and have better measuring performance than the chaotic system.
