| Abstract: | A 1550-nm all-fiber monostatic lidar system based on linear chirp amplitude modulation and heterodyne detection for the measurements of range and velocity is presented.The signal processing method is given,after which the relationship between the peak frequency values in the final signal spectrum,the target's range,and the line-of-sight velocity is obtained in the presence of the fiber end-face-refl ected signal plaguing many monostatic lidar systems.The range of an electric fan as well as the line-of-sight fan speed of different levels is tested.This proposed system has a potential application for the space-borne landing system. |
