Research on the Performance of an Active Rotating Tropospheric and Stratospheric Doppler Wind Lidar Transmitter and Receiver

This paper investigates the transmitter and receiver performance of an active rotating tropospheric stratospheric Doppler wind Lidar. A 532 nm laser was determined as detection wavelength based on transmission scattering aspects. ten-fold Galileo beam expander consisting spherical aspherical mirrors designed produced to compress outgoing laser’s divergence angle using ZEMAX simulation optimization optical-mechanical mounting means. The structure support 800 mm Cassegrain telescope redesigned. Additionally, optimized, size reduced. Meanwhile, detectors fiber mountings were changed improve stability received optical path. single-channel atmospheric echo signal test used select best-performing photomultiplier tube (PMT). Finally, field results original upgraded systems compared. show that after optimizing receiver, altitude system is increased about 47 km, speed direction profiles match better with radiosonde measurements.
