Description

technical field [0001] The invention relates to a laser radar system, in particular to a multi-parameter laser radar system for detecting the three-dimensional space-time distribution of atmospheric particles and adaptable to outdoor complex working environments. Background technique [0002] As an advanced active remote sensing instrument, lidar can monitor a wide range of atmospheric components and environmental parameters (such as temperature, humidity, etc.) continuously, in real time, with high spatial and temporal resolution. Since the first laser came out in 1960, lidar has been widely used in many fields and has become more and more recognized due to its unique technical advantages in detection distance, temporal and spatial resolution, and long-term continuous monitoring. The laser radar system is mainly composed of three parts: laser emission, echo signal reception, data acquisition and processing. Lidar can be divided into many types according to the observation ...
