舰炮发射增程弹道修正弹测量弹道坐标转换

摘要

为了对增程弹道修正弹进行偏差计算、形成修正指令,需要对测量的一段弹道参数进行辨识,目前的辨识算法都是基于相对地球静止射面坐标系的,但是,舰炮发射修正弹以后舰艇继续机动,跟踪雷达随之运动和摇摆.针对舰艇作战环境的特点,建立了舰炮发射增程弹道修正弹测量弹道坐标到射面坐标系的转换模型,并采用基于弹道方程的滤波方法对转换后的坐标数据进行了仿真.建立的模型可以为舰炮发射修正弹的火控软件研制提供参考.%Trajectory parameters are identified in order to calculate error and form correction instruction for extended-range trajectory correction projectiles, and identification algorithms are based the firing coordinate system that is immobile on the earth, but naval vessels continue to move and tracking radars also move and sway after projectiles are fired by shipborne guns. The model is set up that is used to convert measured trajectory coordinates of extended -range trajectory correction projectiles fired by shipborne guns into the firing coordinate system, and converted coordinates are simulated with the trajectory equation filtering. The model is reference to develop fire control software.
