摘　　要：末制导炮弹通过简易的惯性制导系统使弹丸沿直线飞行以达到增加射程的作用。通过研究末制导炮弹惯性制导系统的工作原理,应用MATLAB/Simulink中的Aerospace Blockset,建立了含俯仰和偏航通道的末制导炮弹惯性制导系统简化模型。分析了炮弹惯性制导系统的横向干扰因素及其带来的横向散布。仿真结果验证了模型的正确性,并给出了减少末制导炮弹横向散布的改进策略。The simple inertial navigation system aims to keep the flight path of terminal-guided projectile as a straight line for extending its range. The working principle of projectile＇s inertial navigation system was analyzed, and a simplified projectile＇s inertial navigation mode including pitch and yaw channels was presented in virtue of Aerospace Blockset of MATLAB/ Simulink. The lateral disturbance factors and the lateral distribution in the inertial navigation system were analyzed. The results validate the simplified model. Some strategies are established to reduce the projectile＇s lateral distribution.
