Paper Abstract

We present a pseudo-random-noise modulation, continuous-wave (PRN-cw) total backscatter lidar based on AlGaAs diode laser. The amplitude PRN modulation is introduced by AOM on the cw laser radiation. The detection makes use of a cooled PMT in photon-counting mode. The PRN waveform generator, the data acquisition system and the data processing are steered by the same PC computer. The connections from the laser to the beam-expander and from the telescope to PMT housing are made with optical fibers. Lidar signals of topographic targets, clouds, and the atmospheric return are presented.
