Acoustic modeling and simulation for combined self-guided system of autonomous underwater vehicle

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 AUV 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.
