基于弹道解算的目标数据装定系统

The Setting System Based on Trajectory Solution

针对GPS/INS弹道修正弹射击诸元装定的需要,设计一种基于弹道解算的多功能装定系统。该系统以TI公司的DSP为主控芯片,实现弹道解算、人机交互、指令和数据的收发以及星历和射击诸元数据的存储等多项功能。系统的软件算法核心以3维质点弹道模型为基础,采用牛顿插值法拟合射程修正量与阻尼器展开时刻的关系式,利用差商的方法确定多项式系数,最后采用二分法完成对阻尼器展开时刻的计算,实现对弹载系统的修正指令预装定。实弹试验结果表明:设计的装定器工作稳定,运行流畅,控制方便,能满足修正单射击诸元装定等功能,可为各类相关试验提供基本需求保障。

Due to a variety of disturbances,trajectory correction projectiles can not detect real-time parameters resulting in the loss of correcting.Based on trajectory solution to meet the need of GPS/INS trajectory correction projectiles,this paper designs a muti-function setting system The system uses TI’s DSP as the CPU,achieving the function of human-computer interaction,data transceiver and shooting metadata storage.Based on the particle trajectory model,it uses the Newton interpolation to fit the relationship between the correction range and the start time of the damper,then uses difference coefficient and dichontomy to calculate the start time of damper.The real ammunition tests show that the fitter is stable and convenient,and can improve the missing success rate of correction obviously.
