A Fast Acquisition Strategy of Laser Communication on Airship Platform by Small Divergence Angle Composite Scanning

In this paper, we designed and optimized the ship-to-airship capture scheme of laser communication system according to the characteristics of airship platform. A composite scanning strategy was proposed to solve the problem of the long capture time under the condition of small divergence angle and far distance. The working principle of this composite scanning strategy and the influencing factors in the capture process were analyzed emphatically, meanwhile, LABVIEW was used to simulate the process. It is proved that the capture strategy saved a lot of capture time of dynamic laser communication between the airship and the ship. The simulation results show that the acquisition time is better than Existing modes.
