Problems solved by technology

From October 2016 to March 2018, the ground-based LACROS system in Cyprus conducted cloud, aerosol and precipitation experiments for 18 months using a variety of remote sensing equipment, the main advanced remote sensing equipment including an aerosol LiDAR, a millimeter-wave cloud radar for mixed phase and ice cloud profile measurement and ice water content measurement; China Meteorological Administration is organizing a super-large city test project, in which the cloud observation mainly uses the same test site ground millimeter Boyun radar and lidar conduct collaborative remote sensing observations; the microwave laser collaborative detection schemes adopted in the above projects all adopt the same-site collaborative observation design of microwave radar and lidar, which does not solve the problem of simultaneous high-temporal and spatial simultaneous detection of the same cloud cluster at the same time and in the same direction

Description

technical field [0001] The invention relates to the technical field of measurement and testing, in particular to a miniaturized microwave laser composite detection radar with a common aperture. Background technique [0002] Atmospheric clouds and aerosols play an important role in global climate and environmental changes. Accurate cloud and aerosol information can deepen people's understanding of the earth's energy balance and improve the accuracy of numerical weather forecasting, which is of great significance to climate research. At the same time, a detailed understanding of the spatial distribution of aerosol characteristics is also a prerequisite for understanding the pollution mechanism and controlling pollution. [0003] Cloud and aerosol remote sensing detection technologies mainly include passive detection technologies such as imaging spectrometers, lidar technology and microwave radar technology. Compared with passive remote sensing detection technology, lidar and...
