Three-dimensional Trajectory Simulation of Air Defense Missile based on Matlab

A method for three-dimensional trajectory simulation of air defense missile based on matlab is studied.The guidance law and the trajectory simulation are presented.Taking the proportional guidance method as an example,air defense missile trajectory simulation modeling is established and the three-dimensional simulation of missile trajectory is protracted on Matlab language.The choice of some parameters and its influence on trajectory are discussed among the rest.Finally,the influence of the missile and target velocity including the guidance coefficient on the simulation trajectory and the encounter time are analyzed.The results of simulation show that this method is significant in improving trajectory optimization design.
