基于目标运动估计的越区切换优化策略

Handoff Optimization Based on Target Motion Estimation

地空数据通信系统的越区切换不仅要尽可能地减少切换次数,还要保持地面通信路由优化,以提高地空通信保障的可靠性。通过采用基于加速度的运动估计预测目标位置,并融合最短路径算法确定越区切换站点,在保证地空数据通信质量的同时提高了越区切换的效率,满足空中目标自由机动情况下的跨区域无缝通信要求。

For the handoff of ground-air data communication system,not only handoff times need to be re-duced,but also ground communication route optimization is required in order to improve the reliability of ground-air communication. Based on the prediction of target position and the integration of the shortest path algorithm,the handoff site is determined. With this method,the quality of ground-air data communica-tion is ensured and the handoff efficiency is improved,which meets the cross-regional seamless communi-cation requirement of air targets in free maneuvering state.
