摘　　要：介绍了一种应用Matlab／Simulink进行某空地导弹系统建模的方法，具体分析了风的扰动因素对该系统的影响。该仿真系统中，导弹模型包括了制导控制系统、导引头、导弹动力学运动学等模块，可以完成导弹对目标的截获，追踪，打击的弹道模拟。干扰模型主要针对典型风场，如常值风、大气紊流、风切变、突风进行了分析建模，完成了单风场干扰作用下弹道和参数的仿真实验。实验表明，该模型能够模拟风干扰因素下导弹的飞行弹道，对分析导弹制导控制规律以及弹道散布特征等具有借鉴意义。According to an Air-to-ground weapon system, the article introduces a trajectory modeling method of the whole guided missile system in disturbance of wind field, which developed in Matlab/Simulink environment. The missile system model includes the guidance control system, seeker, the missile dynamics and kinematics models. The article also analyzes the wind field disturbance factors, including atmospheric turbulence, wind shear, gusts, and established the Simulink mod- els. After the system model built up, the trajectory simulation was made in the wind field disturbance. The Results show that this system is well simulated the flight trajectory in different wind field, and can be used for reference when analyzing the similar trajectory modeling.
