利用协方差控制的理论和方法，研究了Ｃ３Ｉ系统中航迹数据融合的未来点相关域预测问题，提出了根据格定预测误差协方差来确定目标航迹未来点所处的相关域位置及大小的新方法。该方法具有实时性好、计算量小的特点。仿真结果表明了该方法的可行性。
Based on the theory and method of covariance control, the future point-related domain prediction problem of the trajectory data fusion in C3I system is studied. The location and size of the relevant domain of the future point of the target track is determined based on the grid prediction error covariance new method. The method has the characteristics of good real-time and small computation. Simulation results show the feasibility of the method.
