Abstract

Simulating real virtual ocean environment is necessary for the research of interaction simulation of underwater gravity aided inertial navigation system. 3D modeling and simulating deep ocean waves are the key techniques to realize virtual ocean environment. JONSWAP spectrum is a deep wind wave spectrum and is suitable for simulating deep-water waves. Based on directional ocean wave spectrum composed of JONSWAP spectrum and directional spreading function, numerical simulation of 3D deep-water waves in the case of different wind velocities is realized using MATLAB. The simulation speed is fast and the effect is good. The simulation can provide some technological supports for interaction simulation of gravity aided navigation system for underwater vehicles.
