Study On Architecture Of Autonomous Mine-Hunting Sonar System

Although there are many kinds of means of anti-mine, the mine-hunting by sonar, which has many advantages such as swift, self-contained and secure, is regarded as the most important means of anti-mine by many national navies.As a new concept weapon platform,the autonomous mine-hunting sonar system has a promising future in the field of ocean exploration as well as military application.Therefore, many countries have poured lots of manpower and material resources into studying it.The autonomous mine-hunting sonar system is a kind of engineering system including many new and high technologies,and every technology it concerned also belongs to the most advanced science and technology.According to the analysis of the system's working environment and work features,this paper presents detailed analysis and depiction of the system's total structure and every function unit,further more makes an farsighted exploration and study of its key technology.The main content is as follows:1.On the basis of detailed analysis of the autonomous mine-hunting sonar system's composition and the elaboration of every composing unit's function,this paper constructs the system's total frame model.Meanwhile,the paper presents the detailed description of system's basic working flow and underwater vehicle's control as well as autonomous operating process, further more makes certain the key technology of the autonomous mine-hunting sonar system.2.This paper analyses the composition of ordinary way of communication and navigation as well as respective merits and weakness ,combining the system's working environment and working features to certify its basic ways of communication and navigation,emphasizing to elaborate technology of submarine communication and integrated navigation.On this condition,it advances the elementary solution plan of the system's communication and navigation technology. 3.Associate with the autonomous mine-hunting sonar system, this paper systemically introduces the basic concept,functional molel,order structure, corresponding algorithm and relevant applied problem of information fusion.At the same time,this paper also elaborates application about multi-sensor information fusion technique in Kalman filter based integrated navigation technique and in mine target recognition.4.This paper combines genetic algorithm with case-based learning method to present a new solution to the optimum path planning of the autonomous mine-hunting sonar system's underwater vehicle,and gives concrete design and realizing method as well as corresponding algorithm.Even though only an exploring research,this plan is proved to be successful and feasible,which makes the autonomous mine-hunting sonar system have the ability of self-navigation,self-avoidance and self-working.5. According to the study of the autonomous mine-hunting sonar system's architecture, the paper designs a project of the autonomous mine-hunting sonar system hardware-in-the-loop simulation, and give the hardware and software's constitution in this project.At the same time, the simulation system's data flow and software architecture are introduced in this paper.
