摘要
舰船辐射噪声是水下目标被动探测的信息源,是声呐和水下攻击武器进行被动目标探测定位和攻击的基础。舰船声特征模拟主要是仿真舰船的辐射噪声,研究和分析舰船的声学特征,建立相应的数理模型,并能够逼真地将这些特征模拟出来。论文通过对舰船辐射噪声产生的基本因素和典型仿真理论的研究和分析,完成对经过多途海洋信道传播后的舰船辐射噪声特性仿真,为今后舰船辐射噪声仿真器硬件的设计打下一个更好的理论基础。
Ship radiation noise is a passive source of information for underwater targets,which is the basis of sonar and under-water attack weapon for passive target detection and positioning and attack. Ship sound characteristics simulation is mainly simula-tion of the ship's radiation noise,researching and analyzing the acoustic characteristics of ships,establishing the correspondingmathematical model,and can be realistic to simulate these features out. In this paper,through the research on the basic factors ofship radiation noise and the typical simulation theory,complete the simulation of the ships radar noise characteristics after multi-channel ocean channel propagation. For the future design of ship radiation noise simulator hardware lay a better theoretical basis.
