摘要
Abstract
In this paper, a theoretical model of the acquisition in intersatellite optical communications (IOC) is founded with the assumption that beacon pointing errors could be modeled as Gaussian random variables. An optimal scan method should be chosen according to the average acquisition time under a certain acquisition probability. With analysis of the most common scan methods during the establishment of IOC, the raster-spiral scanning can substitute the spiral scanning is found. The raster scanning and raster-spiral scanning are simulated using Monte Carlo method and the result shows the first one is optimal for acquisition in IOC.
