目标运动参数误差对舰炮射击诸元精度影响分析

Analysis of Influence of Target Motion Parameter Error on the Accuracy of Naval Gun Firing Elements

为了分析目标运动参数误差对舰炮射击诸元精度的影响,论文分析归纳了目标运动假设模型,诸元求解模型,利用Matlab对弹丸飞行时间、射角与弹道点水平距离进行了拟合;建立了敌我运动状态到射击诸元的仿真分析框架,通过仿真贴近实际的敌我运动状态和雷达观测误差,得到目标运动参数误差与舰炮射击诸元的关系。仿真结果表明:目标匀速直线运动但对目标做匀加速运动假设,高低瞄准角误差在10-3数量级,方向瞄准角误差在滤波处理10s后减小至±0.18ml;目标匀加速直线运动但对目标做匀速运动假设,诸元误差对时间有累积效应,高低瞄准角误差在42s、55s达到1ml、2ml,方向瞄准角误差将于63s达到1ml。

To analyze the influence of target motion parameter error on the accuracy of naval gun firing elements,this paper analyzes the target motion hypothesis model and the element solution model,and uses Matlab to fit the projectile flight time,angle of incidence and horizontal distance of ballistic point.This paper establishes the simulation analysis framework of the enemy-state movement state to the firing elements,simulates the close-to-sense enemy-state movement state and radar observation error,and obtaines the relationship between the target motion parameter error and the naval gun firing elements.The simulation results show that when the target moves linearly at a constant speed but makes a uniform acceleration motion hypothesis for the target,the angle error is in the order of 10-3,and the direction aiming angle error is reduced to±0.18ml after 10s of filtering.When the target acceler⁃ates linear motion but makes a uniform motion hypothesis for the target,the error of the elements has a cumulative effect on the event.The angle error reaches 1ml and 2ml in 42s and 55s,and the direction aiming angle error will reach 1ml in 63s.
