Paper Abstract

In this paper we study the acquisition technology with the antenna scanning in satellite-ground laser links by theoretical analysis and practical experiment. Based on the satellite-ground laser communication system, we first set up the theoretical model and deduce the mathematic expressions of acquisition probability and acquisition time according to the raster-spiral scanning scheme. Then, we analyze factors which might influence the acquisition probability. Different with other research, our study explores the impact of fixed offset errors as well as the impact of the scanning step and scanning speed on the acquisition system in detail. Further, we optimize the average acquisition time by numerical analysis. Finally, we examine the theoretical model in a real acquisition, tracking and pointing (ATP) system. The experimental results showed that the proposed analysis can improve the acquisition performance.
