Abstract

Coherent imaging with multi-beam laser is considered as a key technique in ground based imaging. In the paper, the composition of multi-beam laser coherent imaging system is demonstrated in detail, the constraints between subsystem parameters are analyzed, and the array layout of multi-beam laser imaging transmitter is proposed. In the system, the laser aiming accuracy has an important impact on the imaging. The theoretical simulation indicates that the aiming error of the emitter array should be controlled within 5%. Finally, Design equivalent aperture as Φ1.5m experimental system and Imaging target successfully, verifying the correctness and feasibility of the system, and promoting the implementation of multi-beams coherent imaging technology.
