无人作战飞机数据链延时对攻击决策的影响及其补偿

数据链是无人作战飞机与地面控制系统之间的纽带,但是数据链延时会使地面操作员对战场态势的判断存在滞后和误差,从而易引起决策不当。在分析了无人作战飞机对地攻击过程中数据链延时对攻击决策影响的基础上,采用Unscented卡尔曼滤波器估计了无人机和机动目标状态,然后采用一种状态外推算法和马尔科夫加速度模型分别对二者的状态进行了预测。仿真结果表明,该方法对数据链延时具有较好的补偿作用,可以减少因数据链延时造成的不良影响。

Time Delay of Datalink Effects on the Decision of Attack and Its Compensation

Datalink is the link between unmanned combat aerial vehicles and ground control system,but its time delay brings lags and errors to judgments of the operator on the ground to battlefield,which easily leads to poor decisions.Based on the analysis of effects of the time delay on the decision-making in the process that a UCAV attacks the target on the ground,unscented kalman filter is used to estimate the state of the maneuvering target and the UAV.Then state extrapolation is used to predicte the state of the UAV and Markov acceleration model for the maneuvering target.Simulation results show that the method has a good compensation effect on time delay of datalink,and reduces the adverse impact of time delay of datalink.
