“…In the detection of various meteorological elements, coherent Doppler wind lidar technology is relatively mature. 2,15 With the development of space science and computer science, people pay more attention to the meteorological parameters of the upper atmosphere. Compared with the low altitude atmosphere, the detection of the upper atmosphere is more difficult, and there are more requirements for lidar system.…”

“…Light Detection and Ranging (LiDAR) is an advanced technology that utilizes laser beams and scattered light for precise measurement and observation. In comparison to traditional meteorological sounding methods, LiDAR offers the advantage of non-contact observations, allowing for a wider range of measurements, including higher altitude levels and complex terrain areas [11][12][13].…”

In the study of atmospheric wind fields from the upper troposphere to the stratosphere (10 km to 50 km), direct detection wind LiDAR is considered a promising method that offers high-precision atmospheric wind field data. In 2020, Xie et al. of the Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, developed an innovative rotating Rayleigh Doppler wind LiDAR (RRDWL). The system aims to achieve single-LiDAR detection of atmospheric wind fields by rotating the entire device cabin. In 2022, the feasibility of the system was successfully validated in laboratory conditions, and field deployment was completed. Due to the structural differences between this system and traditional direct-detection wind LiDAR, performance tests were conducted to evaluate its continuous detection capability in outdoor environments. Subsequently, based on the test results and error analysis, further analysis was carried out to identify the main factors affecting the system’s detection performance. Finally, the error analysis and traceability of the detection results were conducted, and corresponding measures were discussed to provide a theoretical foundation for optimizing the performance of RRDWL.

“…Using the law of wind field changes, humans can improve the accuracy of poor weather forecasts (especially low-altitude wind shear) and ensure the safety of aviation flight and the safety of life and property [4][5][6]. Use of Lidar to detect atmospheric wind fields began in 1972, and various wind-measuring Lidars have been used so far [7][8][9][10][11]. The principle is to detect the Doppler frequency shift caused by wind speed and accurately identify the Doppler frequency shift signal carried by aerosols or molecules.…”

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