针对防空作战中空中目标航迹预测的问题,提出一种基于灰色理论的空中目标航迹预测方法.该方法通过建立等维新息残差修正GM预测模型,实现了航迹的实时在线预测,从而提高了预测精度.(method for predicting aerial target tracks in air defense warfare was put forward based on grey theory．establishing the predicting GM model of corrected residual error，on—line prediction of the target track could be realized in real time，and thus could improve the prediction precision.)
