Paper Abstract

Fiber Doppler lidar systems the advantage of high velocity precision over conventional differential velocity measurement. However, the velocity precision of fiber Doppler lidar systems may be degraded by the complex motion of the target, the roughness of the target and the discrete digital data processing. In this paper, a setup of 1064 nm fiber Doppler lidar system is proposed to measure the velocity of radial moving targets. Detailed theoretical analysis was conducted with the influence factors on the velocity precision of the system, and simulations were conducted with an optimized design. A prototype was constructed in the laboratory and experiments were carried out with the prototype. The experimental velocity was 2.65 cm/s, and the relative velocity precision was superior to 0.3%, which proved the validity of the research.
