主要介绍了舰船辐射噪声的生成，包括宽带连续谱和线谱的建模仿真，得到了不错的效果(Mainly introduces the generation of ship radiated noise, modeling and simulation, including broadband line spectrum and continuous spectrum, obtained good results )

说明：  全相位FFT算法是天津大学的王兆华和候正信教授提出的，具有初始相位不变和有效防止频谱泄露的特性，在他的相关书籍上做过严格的证明，并有相应的matlab程序。(All-phase FFT algorithm is proposed by Professor Wang Zhaohua and Professor Hou Zhengxin of Tianjin University. It has the characteristics of invariant initial phase and effective prevention of spectrum leakage. It has been strictly proved in his relevant books and has corresponding matlab program.)
