Full - Ballistic Digital Simulation Technology For Continuous Wave Doppler Fuze

With the progress of times, the radio fuze technology has always been changing, but because of simple structure, small volume, low cost convenient and quick test, the continuous wave doppler fuze still plays an important role in modern battlefield. In order to present a direct and efficient simulation of the degree of destruction on the targeted enemy, this thesis introduces the computer simulation technology and gives detailed description and simulation of the launch of shells, the posture of shells in the air, the fuze doppler echo processing after boot, jamming and anti-jamming of the radio fuze, and artillery range. Using OpenGL technology establish visual dynamic simulation model, showing the shells flying.(1)Firstly establish the ballistic trajectory equation under the standard meteorologic conditions, solving falling velocity and impact angle by fourth-order Runge-Kutta.(2)Based on the cell segmentation method, calculate the targeted areas, if shells hit the ground, calculate the damage air by the overpressure that is caused by the explosion. Quantitative analysis of the area and killing overpressure damage investigate the effect of target.(3) Read antenna a grenade fuze determine its three-dimensional model of graph construction, calculated at each time fuze that spin under the influence of directivity, brought into a continuous wave doppler target detection system, the completion of a grenade decision threshold determination.(4)Based on MATLAB-Simulink constructed a radio fuse typical electromagnetic environment simulation system, rules and irregular waveform signal source of the interference waveform analysis grenades typical electromagnetic environment interference.(5)With the digital graphic display of OpenGL, the establishment of dynamic simulation platform grenades. The simulation platform, grenades and sources of interference parameters are initialized, and then dynamically display grenade from launch to detonation of the entire process, the final result in the output interface display standoff, anti-scope simulation results.
