congratulate!Chinese scientists realize major breakthroughs in the development of lidar systems

Recently, the scientific research team of China University of Science and Technology has achieved significant breakthroughs in related wind measurement of laser radar, and for the first time, it has achieved the highest -time high -speed wind farm observation of the world's highest space -time resolution of 3 meters and 0.1 seconds for the first time. The result was published in the international academic journal "Optical Express" a few days ago.

The atmospheric wind farm detection of rice -level resolution is of great significance in terms of aerospace safety, high -value target guarantee, and numerical weather forecasting. In order to obtain a wind farm with time -space resolution of 3 meters and 0.1 seconds, it is necessary to increase the existing lidar signal signal detection sensitivity of 2 or more. The scientific research team comprehensively optimizes the laser radar on the laser light source, optical receiving system, high -speed data collection circuit and data processing algorithm, and proposes a new reaction algorithm, which greatly improves the accuracy and stability of the wind farm back. A set of nationwide "product -level" test prototypes, which have the characteristics of human eye safety, light equipment (40 kg of equipment), stable work, and strong environmental adaptability.

In order to further test radar observation performance and environmental adaptability, the scientific research team used the radar to measure the wind farm structure in the tail flow of high -speed train at the high -speed train station. The radar continued to work continuously for more than 100 hours under unattended, and obtained 350km/h high -speed rail stream of 350km/h under high -time and space resolution of 3 meters and 0.1 seconds.
