The simulator design of GPU accelerated radiated noise from surface taget

The simulator design of surface target radiated noise is the key technology to test passive sonar systems, target oriented recognition and underwater soft against. The mathematical simulation model of the line and continuous spectrum in frequency domain from surface target has been established based on the description and analysis of radiated noise signal characteristic. Delay acoustic orientated method and one-third octave filter bandwidth algorithm for the simulation of moving target position and information are proposed. The design of broadband FIR filters has been completed. The overall structure of the target noise simulator is real-time implemented by using the widely used GPU (Graphic Processing Unit) accelerated parallel platform. It greatly reduces the consumption of the system hardware resources. It is proved that the simulator can better achieve the characteristics of surface target radiated noise after the mathematical analysis of simulator output. It has a good scientific application value.
