Description

technical field [0001] The invention relates to the technical field of radar, in particular to a device and method for detecting the validity of laser radar data. Background technique [0002] Lidar is an active modern optical remote sensing device, which is an extension of traditional radio or microwave radar to the optical frequency band. Atmospheric detection lidar uses laser as the emission light source, and detects various atmospheric elements by quantitatively analyzing laser atmospheric echo signals according to physical processes such as the scattering and absorption of laser by the atmosphere. Compared with the detection source of traditional radar, laser has the characteristics of high brightness, high collimation and short pulse, which makes lidar have high space and time resolution and high detection sensitivity, which is very suitable for atmospheric detection. Detection and research; lidar is a high-tech integration of laser technology, optics, machinery, elec...

Problems solved by technology

[0004] At present, the atmosphere-related lidar systems used in ecological environment monitoring, meteorological observation, scientific research universities and other fields do not adopt automatic devices for data validity judgment, and rely more on human operation. On the one hand, the workload is heavy, and on the other hand On the one hand, the requirements for the professional quality of the operators are higher, and at the same time, the amount of cross-referenced data is relatively large
