In this paper,firstly,several filtering theory in the fire-control system,such as,curve fitting,Wiener filtering and Kalman filter,is discussed.Secondly,the commonness of the problems of measuring error on statistical characteristic and maneuver target's regularity,which can't be predicted accurately,is analyzed.Thirdly,based on the gray system math model of the gray system theory,the aeronautical maneuver target trace is predicted using dynamic differential fitting model for data processing.In the end,several characters of gray forecasting on aeronautical fire-control system,is given.Such as,both the useful signals and the noise is under consideration.Forecasting value at any moment in any time can be obtained.Series of numbers,which has evident regularity,are produced by the initial data.The residual error identification model is used.The gray predictive control is taken in to account.
