为了减小驾束制导炮射导弹导入段偏差,使导弹启控时尽量靠近波束中心,必须合理设计火炮发射角。结合驾束制导的主要特点,首先分析了发射角设计的要求;并在一定的假设条件和约束条件下,针对该设计要求,利用导弹质心运动学方程和动力学方程,推导出了驾束制导炮射导弹发射角的计算公式;最后利用某驾束制导炮射导弹弹道模型进行了仿真,仿真结果验证了该计算公式的准确度很高。利用该计算方法所确定的发射角范围能够满足导弹导入段的要求,且计算简便。

In order to decrease the deviation from the center of the beam when the missile entering into the beam, it is necessary to design the right artillery firing angle. With the main characteristics of beam riding guided missile combined, first of all, the design requirement of firing angle was analyzed; then under certain constraints, for the above design requirement, using the missile basic equation, this paper derivate the formula of computing the firing angle; finally, based on the trajectory model of a beam riding gun-launched missile, the simulation was carried on. Through simulation results, the accuracy of this method was confirmed. Using this method to determine the firing angle can meet the requirements of design and the calculation is simple.
