Weak Signal Detection in the Background of Chaotic Sea Clutter
Pengfei Du · Systems engineering and electronics · 2002
This paper discusses the detection problem of the weak signal submerged in the background of sea clutter.The classical statistical detection theory taking sea clutter signal as stochastic signal, greatly reduces the capability of signal detection. In this paper,the prior information that the sea clutter is in fact chaotic is exploited. The weak signal submerged in the background of chaos is detected by using neural network's method to restruct phase space. The model error and different signal forms are also considered.The results show that this method can detect the weak signal in the background of chaos effectively.And high improvement factor is obtained.
