| Radar are systematic engineering,the component range,signal processing complexity,it involved many algorithms and parameters.In conventional radar principles and radar systems teaching,because of funding and space constraints,it is difficult to show the kind of radar component modules,or show the radar signal processing aspects of the signal waveform and the characteristics.So the use of semi-physical and simulation system to carry out the radar principle experiment,is a small investment,quick,intuitive,high repeatability technical way.This paper is based on Airborne Doppler radar simulation teaching goal,established a simulation of three-dimensional space,3D aircraft and radar beam model.Especially the application can draw a radar capture range space on a theoretical basis.Provides a realistic airborne radar flight scene,and relatively realistic radar capture process for radar teaching.In this paper,manually draw and aircraft kinematic principle two methods to achieve the aircraft flight path planning,generated management process.OpenGL visual principle in a different view on the use of OpenGL for hand-painted required conditions and interface.And rigid body kinematics principle and OpenGL graphics model transformation matrix calculation method to do the appropriate elaboration.Gives the calculated relative to the target aircraft information capture airborne radar,thus completing the preliminary simulation of aircraft flight path planning and radar target capture.The paper use vs2008 programming environment on Windows system,use cross-platform programming language Qt and OpenGL simulation system overall planning,construction,and implementation process.And optimize the model shows,so that the software has been maintained at a high level in the process of using frames.Similarly,because The software relies programming libraries are cross-platform programming language,making the overall simulation software projects can be compiled to run on different operating systems. |
