Modeling and Simulation for Missile Midcourse-guidance System

This paper takes the background of certain ground to air missile practical application,builds the mathematical model of the missile's motion in the space vertical plane,the radar measuring model and so on.It has designed a software pack for the analysis of midcourse guidance's precision,which includes the initial alignment module and other several modules.The paper introduces the constitution and the realization of every module.With the application of the software,you can get the impact of the initial alignment error and other error on the precision of midcourse guidance,and also you can analyze the midcourse guidance law and ballistic trajectory parameters specially,then make the evaluation of the missile parameters and the whole performance improvement.
