机载空间激光通信平台间跟踪理论研究

Research on Tracking Theory between Airborne Platforms for Free Space Optical Communications

摘要:

随着自由空间光通信应用的深入,以机载平台为节点的激光通信链路已成为研究热点。机载平台的跟踪预测性能决定了通信的成败,机载平台间跟踪预测是一个典型的非线性问题,为解决这个问题,提出了一种改进的粒子滤波方法,且在此基础上,仿真实验验证了该种方法对机动平台具有良好的自适应跟踪性能。

Abstract:

With the wide applications of free space optical communication,laser communication link based on airborne platform has become a hot research topic.Tracking and forecasting performance of airborne platform,a typical non-linear prediction problem,determines the result of communication.In this paper,a modified method based on particle filter is proposed.Simulations proveits good self-adaption performance for airborne platforms.
