一种复合制导导弹的导航滤波器设计

研究了一种中制导段采用雷达修正的遥控制导方式和末制导段采用捷联式自寻的导引头的自导引制导方式的捷联式复合制导的中远程战术导弹的导航滤波问题，考虑到目标的大机动性和模型的非线性，基于最佳估计理论中的广义卡尔曼滤波理论，建立了通用导航滤波方程，仿真计算与仿真结果表明所做设计是合理和有效的。

Design of a Navigation Filter for Combined Guidance Missiles

In this paper, a navigation filter for medium range tactical missiles which use strapdown combined guidance system is studied. Remote guidance updated by radar is adopted in mid guidance stage, and homing guidance using self target seeking seeker in terminal stage. A navigation filter equation, taking high maneuver and linearless into account and on the basis of generalized Kalman filter in optimal estimation theory, is established. Digital simulations show that the schemes can work effectively.
