Acquisition, Pointing and Tracking System for Shipborne Space Laser Communication without Prior Information
文献摘要：
A space laser communication acquisition, pointing and tracking (APT) system based on the beacon laser is designed without prior information. And then, a new target scanning method and a pointing and tracking algorithm are proposed. The target scanning mode is the round-trip triangular wave scanning, and it means that scanning track of the PAN-TILT platform follows the triangular wave repeatedly. For the pointing and tracking algorithm, the beacon laser is used as the auxiliary aiming light source. The position of the beacon laser in the viewfield of the complementary metal oxide semiconductor (CMOS) camera is calculated by the centroid algorithm. In order to realize the target tracking, the joint control method of the angle control and the angular velocity control is used. The simulation and experimental results show that the APT system can achieve full coverage scanning in the scanning area and capture the target in one scanning cycle successfully. After capturing the PAN-TILT platform, the pointing and tracking algorithm can track the PAN-TILT platform quickly and accurately, and the tracking accuracy is up to 0.22 mrad.
