Research On The Simulation Technology Of OODA Buoy Sonar In A Confrontational Situation

Now,for a specific academic problem or problem that needs to be solved in engineering,researchers often give a variety of solutions in the early stage,and after a lot of practice to find a best solution.However,from a practical point of view,not all solutions to problems can be verified in practice.A buoy sonar system that requires a naval warfare coordination can not simulate the scene of a real battle to verify the performance of the buoy or the performance of the positioning algorithm.Therefore,simulation is a good way to verify system performance without the need for facts.By implementing the system simulation to be detected on the computer,the performance of the buoy related technology can be well tested.Simulation has slowly become the focus of research.This paper introduces the simulation principle of DIFAR buoys and LOFAR buoys.From the perspective of signal level,for the DIFAR buoy,the simulation of a single DIFAR direction finding algorithm and two DIFAR DIFIX positioning algorithms is introduced and completed.The LOFIX positioning algorithm was introduced and completed for the LOFAR buoy.The OODA(Observe Orient Decide Action)theory is used as the research angle to study the relationship between the detection range of the passive buoy sonar and the sound velocity profile,the working depth of the buoy and the target characteristics of the submarine.In this paper,the influence of two typical sound velocity profiles on sound propagation is analyzed by BELLHOP model.The influence of the depth of passive sonar buoy on the detection distance of submarine is analyzed when the submarine is at different depths.Through simulation research,it can be obtained that when the buoy works at every certain depth,when the local submarine appears,whether the buoy can effectively explore the target is regular,each depth corresponds to the specific detection performance and Maximum detection range.Therefore,understanding this special law has a great effect on the performance of excavating buoys and scientifically improving the efficiency of use.In this paper,the underlying algorithm of signal-level buoy simulation is implemented on the third-generation underwater acoustic equipment signal processing equipment with superior computing performance.The third generation of underwater acoustic equipment signal processing equipment is a parallel computing system consisting of a large number of TMS320C6678 multi-core processors.In the whole buoy sonar system,the real-time parallel operation of multi-buoy and multi-channel hydrophone digital signals is completed.Sending the processing results to the display console greatly improves the computing power and performance of the sonar system.In the environment of underwater acoustic confrontation,the detection response of the buoy sonar to the submarine target and the underwater acoustic countermeasure equipment is completed.The Qt realizes the system’s guidance and display interface functions,and tests its stability,accuracy and acceleration performance,which lays a foundation for improving the development efficiency of the buoy sonar system simulation technology.
