| Abstract: | 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. |
