Design And Realize Of 3D Situation Display System Of Integrated Console Of Flight Simulator

Situation display have been used in military command and decision,as one of the most important decision methods.With the new-tech equipment being greatly used in military struggle,especially the requirements of the information,base,simulation training and the modern war in military struggle preparation,the effects of 2D and 3D situation display is becoming more and more predominant in command decision.In the simulation system of military training,technical implementation of Situation display,is especially the main technical means to achieve the system demand and function.The paper is worked on the 3D situation display of the console desk in the flight training simulation system,and is divided into five chapters.The first chapter introduces the academic background,the development status and the main problems of the 3D situation display field and the main contents of this paper.The second chapter is mainly worked on the definition and characteristics analyzing of the 3D situation display elements.We defined two main concept of displaying technology which is geographic domain and event domain,and proposed the technical route of 3D situation display which is building the database of geographic domain,event domain and scenario domain--programming to call and evaluate many domain of the database--using mature software platform to achieve the display function.The third chapter described the technical route of the scenario content and structure of the target,the scenario database,the scenario generation and the scenario motion in detail.The fourth chapter described the logical relationship of various elements of the low atmospheric flow field,modeling of atmospheric flow field database and the technical route of the development of the simulation software.The fifth chapter focused on the formations of the electromagnetic sensor database,the modeling methods,the assignment methods and the software programming methods in the electromagnetic environment simulation.In the conclusion of the paper,we further elaborated the geographic domain and event domain first defined in the field of 3D situation display technology emphatically,and pointed out the application value and practical significance in the military field.The technical realization way of the 3D situation display of the console desk in the flight training simulation system in the paper is the engineering experience summary of the author and his team,which is a valuable reference.Some of concepts and methods proposed in the paper have gain the national defense patent right and some of them are being accepted and announced.Using or referencing,please obey relevant laws.
