Modeling and Simulation for Missile Midcourse-guidance System

文中以某型号地空导弹实际应用为背景,建立了导弹在空间垂直平面运动的数学模型,雷达测量模型等。设计出了分析导弹中制导段精度的软件包,软件包由初始对准模块等多个模块组成,介绍了各个模块的组成及实现。应用本软件可分析初始对准误差等各项误差对中制导精度的影响,也可用于分析设计中制导律和弹道参数,从而进行对导弹参数设计的改进和整体性能的评估。

This paper takes the background of certain ground to air missile practical application, builds the mathematical model of the missile＇s morion in the space vertical plane, the radar measuring model and .so on. It has designed a software pack for the analysis of midcourse guidances 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 alignmem 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.
