Abstract

Free space laser communication based on airborne platforms will play a important role on the future space communications, high precision tracking system for airborne laser communication has been already the one of the best difficult problem. Because of diversity of maneuvering forms and high nonlinear problem, it is usual to adopt multiple models algorithm with a fixed structure for tracking system, which brings unnecessary inter-competition among the amount of models and calculation burden, in order to resolve this contradiction, a variable structure multiple-model (VSMM)based on digraph switching is presented, the particle filter (PF) can deal with nonlinear/non-Guassian problems, it can be introduced into VSMM framework. Simulation results show that the algorithm improves the accuracy of tracking by reducing the competition of the models as well as reducing the computation burden.
