通过分析旋转导弹的控制原理 ,从弹体舵面产生的周期等效控制力与导引头输出的误差信号之间的方位误差和幅值线性度两个方面 ,提出了一个最优的线性化信号与主控信号的频率比。建立了刚体弹道仿真软件 ,以某型防空导弹为背景进行了一系列的仿真计算。仿真结果表明 ,这一最佳频率比大大提高了导弹的制导精度 ,减小了脱靶量。 By analyzing the control principle of the rotary missile, an optimal linearization is proposed from the aspects of the azimuth error and amplitude linearity between the equivalent control force generated by the projectile surface and the error signal output from the seeker. Signal and the main control signal frequency ratio. A rigid body trajectory simulation software was established and a series of simulation calculations were carried out on the background of a certain type of air defense missile. The simulation results show that this optimal frequency ratio greatly improves the missile guidance accuracy and reduces the miss distance.
