采用分段思想的中段弹道预测算法

针对传统弹道预测方法存在的不足,提出了基于分段思想的弹道轨迹预测改进方法。介绍了中段弹道预测的一般方法,并对其误差产生的原因进行了分析;提出分段的思想,即将前一段新获得的预测终点作为下一段预测的起始点,来减少预测误差的积累,进而给出弹道轨迹预测的改进方法。对相关算法和流程进行了仿真验证及结果分析,结果表明:改进后的预测方法比传统方法误差减小了19%,验证了所提算法的有效性。

An Algorithm of Trajectory Prediction Based on Subsection in Free Phase

Aimed at the insufficiency of the traditional trajectory prediction, an improved method of trajectory prediction based on subsection is given. First, the general method of trajectory prediction in free phase is introduced, the causes of trajectory prediction error are analyzed. Then an idea of subsection is put forward, which turns the prediction end point of the former part to the prediction start point of the next part for the purpose of reducing the accumulation of prediction error, in this way, the improved method of trajectory prediction is obtained. Finally, the relevant algorithms and processes are simulated and analyzed, the results show that this method is reasonable and effective in reducing the error of trajectory prediction.
