Abstract

Miniaturization is the development direction of space payload. In this paper, an integrated laser communication and lidar system is proposed. The laser communication and lidar share a hardware system, and the laser is modulated by BPSK, Chirp amplitude-modulated laser is used, and optical coherence zero-difference detection method is adopted to obtain the target range and velocity information, the composition and working principle of the system are introduced briefly, the laser communication link is analyzed, and the target detection performance under different conditions is studied. Theoretical analysis and simulation results show that the integrated scheme is feasible and effective, the communication rate can reach 2Gbps@(60000km,1E-7), and the effective detection range of space debris can reach more than 50km.
