Research And Implementation Of Laser Fuze Digital Simulation Platform

The traditional method for designing and testing laser fuze requires using a substantial amount of missiles. In order to overcome the resulting high cost and low efficiency, a digital simulation platform was implemented to help the design and testing of laser fuze ,by using the VR technology.Based on the principles of initiative laser fuze, the framework of the simulation platform was designed, and the major functional modules of the platform were developed. The platform could change the simulation model from general .3ds format to surface (a set of triangle planes with directions) data format automatically. By saving the surface data to database, a scalable, manageable simulation model base was achieved. The surface data in model base could be directly used to simulate the fuze process and calculate the laser reflection energy.The platform implemented a wizard to help the establishment of three-dimensional coordinates of simulation scenario, the import of simulation models and the input of simulation parameters. The platform uses MFC and OpenGL technology to emulate the entire process of missile hitting the target. During the animation, the real-time laser reflection energy was calculated, as the reason for detonating the missile.Real-time calculation of the laser reflection energy was key technology of the platform. By establishing a new reference frame, whose origin was at the center of the target, the time for calculation was effectively reduced. The calculation process included the surface division of target by quad-number tree data structure, the irradiation judgment of the divided surface, and the summation of reflection energy from every irradiated area.Finally, function of the platform was tested to verify the work of this paper.
