Design Of Application Demonstration System For Underwater Platform Penetration Route Planning

Due to the important role and position of underwater acoustic countermeasure in naval warfare,the major naval powers in the world have invested considerable human,material and financial resources in the research of underwater acoustic countermeasure technology.With the development of sonar detection technology and torpedo weapon technology,underwater acoustic countermeasure technology has gradually matured.Underwater acoustic countermeasure technology includes defensive countermeasure and offensive countermeasure.China has done more in-depth research on defensive underwater acoustic countermeasure technology,but less involved in offensive underwater acoustic countermeasure technology.In recent years,the research on offensive underwater acoustic countermeasure technology has been gradually strengthened.Aiming at the command decision-making problem of underwater acoustic attack countermeasure,this paper carries out the design and research of underwater platform penetration route planning algorithm and its application demonstration system,and forms a set of simulation model and software system to provide basic support for underwater acoustic attack command decision-making and countermeasure system development.Firstly,the paper introduces the basic models and data involved: the target characteristic model of underwater platform,mainly the target radiated noise level and target intensity,considering their frequency variation and directivity,gives typical data examples;In the aspect of marine environmental parameter model,the hydrological environmental parameter data,seabed terrain data and seabed sediment data of the sea area around Taiwan island are collected,and the reflection loss model of rough sea surface under the influence of wind and waves is given;In the calculation model of sound propagation loss,several sound field algorithm models such as normal wave,parabolic equation and Gaussian beam tracking are introduced to meet the needs of sound field calculation in different situations.Then,based on the sonar equation,the evaluation method of the detection range of our underwater platform by the active sonar system of the opposite underwater acoustic measurement ship and the passive detection sonar of the underwater warning system is established.At the same time,the acoustic concealment evaluation method of our underwater platform is also given to support the route planning and design and master the underwater acoustic countermeasure situation.Finally,based on A*algorithm,a route planning algorithm for underwater platform to break through the other party’s blockade area is proposed;Using QT software,the module design and algorithm implementation of the route planning application demonstration system are carried out.According to the typical combat scenario,the route planning example is given to realize the situation display of the underwater platform breaking through the blockade area and the optimal selection of the route.
