Research On Sonar Detection Capability Based On Ocean Data

As the main means of acquiring information in the ocean,sonar plays a pivotal role in the naval battlefield.How to maximize the effectiveness of sonar is the key to gain advantages,and the use of simulation technology to study underwater sound propagation of underwater sound field simulation technology is an effective way to test and improve sonar.However,due to the complex marine environment,there are certain deviations between the simulation results and the actual application,so how to combine the real marine environment to assess the detection capability of sonar has become a problem.Based on this,this paper researches the processing method of ocean environment data and constructs an ocean database that meets the computational requirements and can be quickly queried to provide data support for real-time assessment and accurate prediction of sonar performance and improve the detection capability of sonar.In this paper,we design and implement a prediction software for acoustic detection capability based on ocean model prediction data,which provides basic support for sonar use and combat-aided decision making.The main work of this paper is as follows:(1)The assessment of the comprehensive performance of sonar is a comprehensive application of multiple technologies.The data sources for sonar evaluation are studied,and a technical solution for sonar detection capability forecasting based on the simulated ocean data of ROMS(Regional Ocean Modeling System)is proposed and the principle of ROMS model is explored,which provides some reference for real-time sonar detection capability forecasting.(2)Research on marine environmental data processing and database construction.A data format file is designed to simplify the marine data by analyzing and summarizing the marine environmental data detected by the impact acoustic sounding equipment;and an inverse distance weighted averaging method combined with the first averaging and then interpolation method is proposed to realize the assimilation processing of the simplified data.(3)Active sonar equipment detection capability research analysis.From the sonar equation,the model of active sonar detection is established;and the optimal operating conditions and distance estimation of active sonar are obtained through experimental simulation,which provides a theoretical basis for the subsequent sonar performance prediction.(4)Research on sonar detection capability forecasting technology.By fusing the ocean numerical model,hydroacoustic propagation model and sonar detection model,the ROMS-based acoustic detection capability forecasting software is realized,which is of great significance to the sonar detection capability forecasting.
