Abstract

The establishment of satellite-to-ground high-speed laser communication link needs to maintain high speed, high precision and high sensitivity, but the beacon signal becomes weaker following the ultra-long-distance transmission between the sending end and receiving end. Considering the problem of rapid attenuation of free space communication optical signals in the future development of high-orbit inter-satellite and inter-satellite transmission, this paper proposes a method of dynamic range compression modulation of coded aperture to improve the accuracy, rate and sensitivity of optical signal imaging acquisition in high-speed laser communication links. Further combined with coordinate system correction, highspeed, high-sensitivity and high-precision satellite-to-ground laser tracking and communication link maintenance can be achieved. Finally, the feasibility of dynamic range compression modulation of coded aperture for optical communication measurement is verified by the design and simulation of laser communication beacon optical modulation matrix, which provides the possibility for its wide application.
