| 摘 要： | 研究了舰船辐射噪声的倒谱信息．倒谱可以避免连续谱特征的不稳定性，基于此，将倒谱代替连续谱作为舰船辐射噪声识别的特征，并对实测的海上数据进行了仿真实验．结果表明，该方法可以有效地达到识别舰船辐射噪声的目的，且识别率高．

| Abstract: | The cepstrum feature of ship-radiated noise is studied. The cepstrum is used as the recognition feature of ship-radiated noise to replace the continuous spectrum, which can avoid the unsteadiness of the latter. The simulation results show that the method can recognize the ship-radiated noise effectively, and has higher recognition rate. |

| Keywords: | cepstrum continuous spectrum ship-radiated noise object recognition |
