摘要
以舰船辐射噪声的包络谱分析为基础,讨论了舰船包络谱的特点和提取的方法。据此提出了一种新的目标识别方法。该方法能有效提高舰船噪声识别系统的识别准确率,还可同时获得有关目标舰船的重要运动要素。
On the basis of enveloping spectrum analysis of ship-radiated noise, the methods to extracte the features from it are discussed. Then a new method of moveable state recognition has been put forward with founded recognition system. Using this method correct recognition rate for different types of ship targets can be effectively improved, and some of important parameters of target's movement can be obtained at the same time.
