水下航行器组合自导系统声学建模与仿真

Acoustic Modeling and Simulation for Combined Self-guided System of Autonomous Underwater Vehicle

组合自导是新型水下航行器制导系统的发展方向,通过仿真手段对其性能及技术特点进行研究是水声仿真研究领域非常关心且亟待解决的问题。对水下航行器组合自导系统的功能及系统构成进行了研究,基于层次化、模块化的建模原则,将组合自导系统分解为13个相互独立的模块,给出了主要模块的数学模型,并利用Visual C++平台在声信号层次上设计并建立了水下航行器组合自导声学仿真系统,仿真结果表明了各模块及整个仿真系统的正确性和有效性。

Combined self-guided is the trend of the development of the guided system in new-type autonomous underwater vehicle （AUV）. The study of the capability and technical character of combined self-guided system （CSGS） by simulating method is an attractive and unresolved problem in the field of acoustic simulation. Based on the study of the function and structure of CSGS and the principle of hierarchy and modularity, the CSGS was divided into 13 independent modules and the mathematic model of main modules was given. Acoustic simulation system of CSGS of A UV was established on the depth of the acoustic signal by using the platform of Visual C＋＋. The simulation results validate the correctness and validity of the modules and the whole simulation system.
