Design And Realization For Analysis Software Of Ocean Ambient Noise Data Based On The Vector Hydrophone

According to the ocean ambient noise data recorded submersible buoy system based onthe vector hydrophone, a set of analysis software of ocean ambient noise data is designed andrealized. The software, which can configure the hardware of the submersible buoy acquisitionsystem, manage and process massive data, and output analysis report, has been tested andverified by actual sea test data. The work in thesis is followed:Firstly, in the light of submersible buoy system’s overall demand for the software,combined with the characteristics of the noise vector field, the thesis gives the overall designfor the analysis software of ocean ambient noise data. The interactive interface based onLabWindows/CVI virtual instrument development platform is devised, the overall structureand the algorithm flow of the software are defined, and the functional modules of the software,including system configuration, data management, data analysis, are detailed designed.Secondly, data processing algorithms based on the vector hydrophone is given, andsimulates how the parameters affect the data processing algorithms on computer, thusprovides basis for parameters setting and selecting in data analysis software.Finally, key technologies used in the process of realizing the data analysis software arestudied in the thesis. To meet the demand of the multi-tasking data analysis software,multi-threading technology is used to solve the problems that the software is hard to respondto operation and perform other functions during the data is processing. To solve the problemthat graphic display costs large memory caused by large amount of data of the submersiblebuoy system, the peak display algorithm is designed, which can not only display theinformation fully but also reduce the amount of data in drawing. The thesis also solves theproblems in the process of data analysis software called applications such as Word. The studyof the software implementation techniques not only helps to improve the performance of thesystem, but also provides new skills and ideas for the development of similar software.The thesis realizes the target functions for analysis software of ocean ambient noise. Thesoftware runs smoothly in joint commissioning with the hardware in the laboratory, and thedata processing algorithms are effective and feasible.
