Paper Abstract

Nowadays LADAR system set on practical moving platform is purposed to detect real-time velocity as well as precise distance and direction evaluation for safe landing or obstacles avoiding. On account of narrow band, brief algorithm, non-modulated CW Doppler LADAR based on optical heterodyne principle could acquire the velocity of multiple targets with high frame frequency, high SNR ratio while no velocity ambiguity. In this paper, a non-modulated 1064nm CW Doppler fiber LADAR system with high frame frequency as well as high velocity precision is proposed. The experimental result of the system shows a velocity precision of 6.65mm/s, and a velocity detection frame frequency of 20FPS, which essentially meet the practical demands.
