| Abstract: | The chaotic detection principle for the signals of ship is given.Based on analyzing the chaos action of duffing equation,the chaotic detection model for the signals radiating from ships is made,and the influences of noise to that detection method are analyzed.The simulation experiment for the signals of ship is made by chaotic detection method.These results of simulation experiment shows that this detection method is more effective than traditional detection method. |
