Research on communication performance optimization between two aircrafts with high maneuverability

针对飞机在高机动条件下进行定向窄波束通信易中断的问题,提出了一种机间定向通信的波束互锁算法。首先利用坐标转换对机间相对位置进行矢量分析,构建高机动飞行下双机通信系统模型,然后对飞机姿态测量、定位、飞机相对运动对波束互锁精度的影响进行分析,最后给出涵盖对准误差的波束互锁算法,实现通信性能优化。仿真结果表明,改进算法能精确反映出高机动条件下通信窄波束偏离目标的程度,帮助通信双方实现快速对准。相比静止条件下的通信性能优化方法。

In order to solve the problem of narrow beam communication easy to interrupt under the condition of high mobility,this paper proposes a directional beam interlock algorithm of communication between planes. First of all, coordinate transformation was used to analyze the aircraft position vector analysis and build the high maneuver communication system model. Then the attitude measurement,positioning of aircraft, and aircraft relative movement＇s influence on the precision of beam interlock were analyzed. Finally, the beam interlock algorithm including the alignment error was obtained, and the communication performance optimization was realized. The simulation results show that the algorithm can reflect the extent of beam deviation from target, help both sides to achieve rapid alignment, compared with the communication performance optimization method under static conditions.
