舰载跟踪雷达测量弹道修正弹坐标转换模型

摘要

弹道修正弹是目前信息化弹药的研究热点之一,为了对舰炮发射修正弹后的实际弹道与预定弹道进行比较、形成修正指令,建立了舰载雷达所测量的相对弹道到相对地球静止的绝对坐标系的转换模型,解决了舰炮发射修正弹以后舰艇继续航行,雷达随舰艇运动、摇摆和升沉对测量弹道的影响.仿真结果证明,该模型是可行的,可为进一步研究弹道辨识问题提供依据.%Trajectory correction projectile is a hotspot of information-based ammunition at present. To compare factual trajectory with theory trajectory of the projectile fired by ship borne gun, and to create correction instruction, the model is set up that is used to convert the relative trajectory coordinates measured by ship borne tracking radar into the absolute coordinate system that is immobile on the earth, and solve problems of measuring trajectory, because of warship navigating, sway and fluctuation. The model is proved by simulating to be practicable and reference to make further research on trajectory identification algorithms.
