基于数据链的空战目标运动参数的转换

为了解决多机协同空战中数据链延时对空战态势判断带来的影响，本文应用了一种极坐标系下的卡尔曼滤波算法，对数据链的传输延时误差进行补偿，并在此基础上进行目标运动参数的转换，计算工程技术人员感兴趣但机载测量设备无法测量的目标信息，比如目标进入角。仿真结果表明，该算法对数据链延时的补偿误差较小，并能对数据链提供的目标数据进行比较精确的处理。

Transformation of target motion parameters in air combat based on tactical digital information link

In order to eliminate the effect of time delay of tactical digital information link(TADIL) on situation judgement in multifighter cooperative combat,we use a kind of Kalman filtering algorithm in polar coordinates to compensate for the error of time delay resulted from data link transmission.And then we implement the transformation of target motion parameters and calculate out the other target information such as target aspect angle,which is useful but cannot be measured by airborne equipment.The results of simulation indicate that the compensating error of time delay is small,and the method can process the target information supplied by TADIL accurately.
