Acoustic Model and Implementation of Multi-Target Homing System for Torpedo

多目标自导系统是新型鱼雷制导系统发展的必然趋势,是对现有自导系统功能的完善与提升,通过建模手段对其性能及技术特点进行研究是自导研究领域非常关心且亟待解决的问题。该文对鱼雷多目标自导系统的功能及系统构成进行了研究,并从系统层面对其关键技术进行了讨论。基于层次化和模块化的建模原则,将自导系统分解为彼此独立的11个功能模块,利用Visual C++平台在声信号层次上设计并建立了鱼雷多目标自导声学仿真系统,给出了主要模块的声学模型。最后,在相同的复杂对抗环境下对多目标自导系统和传统的单目标自导系统进行了100次统计仿真试验,结果表明,多目标自导系统较传统的单目标自导系统命中概率提高了38.5%,航程损耗减小了17.6%,显著提高了复杂对抗环境下自导系统的作战效能。

We analyze the function and structure of multi-target homing system （ MTHS）, and discuss the key technologies of MTHS at the level of system. The MTHS is divided into 11 independent modules based on the principle of hierarchy and modularity. An acoustic simulation system of MTHS for AUV is established at the level of acoustic signal by using the platform of Visual C ＋ ＋ ,and the relative acoustic models are given. Moreover, 100 simulations are conducted to compare the signal-target homing system（STHS） with MTHS in same decoy environment, and statistical result shows that the hitting prebability and range loss of MTHS are respectively 38.5% higher and 17.6% lower than those of STHS.
