Design And Implementation Of Underwater Cooperate Target Positioning System Simulation Software

Underwater acoustic positioning and navigation is the core technology of underwater target tracking.With the increasing emphasis on ocean resources development and maritime rights and interests in various countries around the world,underwater acoustic positioning and navigation usher in new challenges and opportunities for development.The marine environment is intricate,in order to simulate the real marine environment as much as possible.First of all,based on the theory of ray acoustics,the physical problems of underwater acoustic channel are simplified,and the multi-path channel model under the assumption of flat interface and stratified ocean medium is constructed.Underwater cooperation target positioning system composed of a large platform,in order to simulate the system as much as possible the entire working model in the simulation software to add a signal detection module.Single-channel adaptive notch filter can effectively extract the single-frequency signal,but for a number of line spectral components,the performance decreased significantly.Underwater cooperation target positioning system simulation software is based on Qt application software developed under the Windows system.First of all,according to the demand analysis of the simulation software in the underwater monitoring and control equipment networking system,the overall framework of the simulation software is designed and built.Based on the software modular design concept,the design ideas of each module and the key means are introduced.In order to fully verify the simulation software in the various functions and the correctness of the software algorithm.and then performing joint adjustment with the fusion software of the underwater measurement and control equipment network to verify the functionality and stability of the simulation software.Finally,the effectiveness and correctness of the algorithm in the simulation software of underwater cooperative target positioning system are proved,and the function validity and stability of the simulation software are proved.
