基于外弹道的防空火控改进算法及模型仿真

Improved Algorithm and Model Simulation for Anti-aircraft Fire Control Based on External Ballistics

为改善火控系统射击诸元解算的速度和准确性,在设计防空火控解算系统各个模块的基础上,对传统迭代-修正算法进行了改进。首先搭建了基于某型火箭弹的防空火控解算系统;其次对火箭弹外弹道解算问题和典型运动目标的命中问题进行研究;然后在解算流程中引入了目标高低角与目标运动时间关系式,使得在射击诸元解算流程中始终将目标视为运动状态,改变了传统方法中“先静后动”的解算流程;最后搭建了火控解算系统Simulink模型,对传统算法与改进算法进行仿真分析,证明了改进算法可以更加快速、精准地解算射击诸元,为防空火控命中点与射击诸元解算研究提供了一定的参考。

In order to improve the speed and accuracy of the fire control system,the traditional iterative-correction algorithm is improved on the basis of designing each module of the air defense fire control solution system.Firstly,an air defense fire control solution system based on a certain type of rocket is built;secondly,the rocket external ballistic solution problem and the hit problem of a typical moving target are studied;then,the relationship between target height angle and target motion time is introduced in the solution process,so that the target is always considered as a moving state in the shooting plurality solution process,which changes the"static first and then moving"solution process in the traditional method.Finally,the Simulink model of the fire control solution system is built,and the simulation analysis of the traditional algorithm and the improved algorithm proves that the improved algorithm can solve the firing elements more quickly and accurately,which provides a certain reference for the research of the air defense fire control hit point and firing element solution.
