Portable Antiaircraft Missile Trajectory Simulation Technology Research

Since the 1950s, began its development of the portable antiaircraft missile since with its light quality,cheap, easy to carry, operational characteristics such as flexible universal attention by all over the world. Therefore, many countries around the world are working to develop portable antiaircraft missiles. And in portable antiaircraft missile development process, the simulation technology plays a key role. The simulation technology can be simulated experiments missile guidance control system in real tactical environment under dynamic working condition, the only flight test is besides the guidance control system can understand the technology, closed-circuit work live has become a portable antiaircraft missiles system optimization design and the necessary method of the performance of the system.This thesis aims to the task requires of the portable antiaircraft missile, MATLAB/SIMULINK simulation platform for missile trajectory simulation research, mainly completed the following work:1.Introduces the portable antiaircraft missile structure, characteristic and the working process, and on the basis of the portable antiaircraft missile trajectory simulation of main content and basic request and the working process were discussed, for missile trajectory simulation laid a theoretical foundation.2.Introduction of the portable antiaircraft missile trajectory established the mathematical model used, and analyzes the coordinate system coordinate the relationship between the missile and then establish the motion equations, target motion equations and m issile target relative motion equations3.In the establishment of the ballistic mathematical model based on MATLAB/SIMULINK tool to build a missile centroid movement respectively the dynamics module, missile rotating dynamics module around the centroid of mass movement, missiles, missiles kinematics module around the kinematics module, mass rotation Angle of missile each relationship between modules and target motion module.4.In clear VV&A basic principles and general process, and on the basis of VV&A technology using of the portable antiaircraft missile ballistic mathematical model and simulation model into the validation and checking, the reliability of the models is proved and effectiveness.
