The space-borne laser detection system has the capability to detect the vertical profile of clouds and aerosols. Exist-ing payloads, such as the Caliop radar on the US Calipso satellite, the multi-beam LiDAR on the domestic "Goumang" satellite, and the atmospheric detection lLiDAR on air pollution monitoring satellites, are limited to single-beam cloud-aerosol detection with a narrow detection area. A proposed solution is a multi-beam cloud-aerosol detection LiDAR system that operates in a satellite orbit of 800 km and utilizes a multi-beam detection system to extend radar coverage to 30 km. The central beam employs dual-wavelength polarization detection for obtaining vertical profiles and particle species of atmospheric aerosols and clouds, while the edge beam uses single-wavelength detection for cloud profiling. This approach significantly improves data acquisition efficiency through simulation-based verification of dynamic range and high sensitivity single photon detections which reduce laser energy require-ments, as well as radar weight and power consumption. Finally, through simulation, the detection effect of space-borne multi-beam cloud-aerosol detection radar on typical clouds and aerosols is verified.
