分段残差修正改进GM（1，1）模型在方位序列预处理中的应用

Segmentation GM （1, 1） Model in Forecast of Azimuth of Target

对方位序列进行预处理对于潜艇作战具有重要的实际意义．应用灰色系统理论，以改进初值和背景值的GM（1，1）模型分段对目标序列进行预测，可有效克服目标方位序列的非线性和非稳定性，在信息较少的情况下达到精度较高的预处理效果．通过实例计算表明，上述计算可快速提供精度较高预处理结果，为潜艇作战提供有利信息．

The forecasting of azimuth sequence is very important for submarine. Based on modified the initial condition and background value GM（1,1） segmentation model Using Grey System to forecast azimuth sequence, can overcome the non-linear and non-stability of the azimuth sequence, getting the better forecasting result in the case of little information. An example is given to show that, the model can forecast the more precision result in long time, and offering the profitably information for submarine.
