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。 With the application of optical communication in free space, the laser communication link based on airborne platform has become a research hotspot. Tracking performance of airborne platform determines the success or failure of communication. Tracking prediction between airborne platforms is a typical nonlinear problem. To solve this problem, an improved particle filter method is proposed. On the basis of this, simulation experiments It is verified that this method has good adaptive tracking performance to the mobile platform.
