The Simulation of Tow Ship Noise on Towed Linear Array
View through CrossRef
Based on the acoustical properties of the tow ship noise, this paper studies the effect of tow ship noise on the towed linear array sonar system by computer simulation. The tow ship noise which is fairly approximate to the truth tow ship noise is obtained by the typical mathematical mode simulation firstly. Then the near-filed characteristics of the tow ship noise are simulated by using a simplified channel model. Finally, this thesis studies the interference of tow ship noise through beam-forming. The simulation describes acoustic characteristics of the tow ship noise well, and also provides a good theoretical support for the other simulation systems designs.
