基于灰色系统预测直升机航迹的研究

 反直升机智能雷对直升机航迹的预测在作战中非常重要,但在数据非常有限的情况下,准确地预测又很困难。提出了用灰色系统理论解决直升机航迹预测问题,建立了灰色系统 GM预测模型和 n次累加残差模型并对GM预测模型进行修正。在每个采样期间内,实时在线建立GM预测模型和残差模型以提高预测精度。通过实例计算能看出用较少的探测数据可以得到较高的预测精度。

PREDICTION OF HELICOPTER TRACKS BASED ON GREY SYSTEM THEORY

The prediction of helicopter tracks for anti\|helicopter intelligent mine is very important in a battle. However, it is very difficult to get an accurate and reliable prediction when the data is very limited. The paper makes use of the theory of grey systems to predict helicopter tracks, establishing the GM model of grey systems and the cumulative residual error model of \%n\% degrees, then correcting the GM forecast model. In the period of sampling, GM model and residual error model have been established on line to improve prediction precision. The calculation of living examples indicates that higher prediction precision can be obtained with fewer surveying data.
