Laser radar system and observational method for observing atmosphere ozone

Abstract

The invention relates to a laser radar system for observing atmosphere ozone. The laser radar system comprises a main controller, a laser transmitting device set, a laser signal detector, a light beam combiner, a data acquisition device and a terminal device. The laser transmitting device set comprises at least two groups of laser transmitters, the main controller respectively controls each group of laser transmitter, and transmitting terminals of the laser transmitters are respectively connected with input terminals of the light beam combiner, so that difference absorbing observation and analysis on the atmosphere ozone are performed simultaneously through multiple wavelengths, and high-efficiency and high-accuracy experimental observing effect is realized. Correspondingly, the invention further relates to an observational method of the laser radar system for observing atmosphere ozone. The observational method is based on the laser radar system to realize the difference absorbing observation and analysis on the atmosphere ozone, so that working efficiency of the actual difference absorbing observation is effectively guaranteed.

Description

technical field [0001] The invention relates to a laser radar system and an observation method for atmospheric ozone observation. Background technique [0002] At present, the main detection method of atmospheric ozone is to use differential absorption lidar technology, but there are still the following problems: in the prior art, a fixed wavelength is generally used to observe atmospheric ozone, and the same experimental observation process is due to laser output , The instability of the laser radar echo signal, the instability of the detector signal, and the instability of the atmospheric conditions and other factors are not considered. Even if the random error is considered, it is necessary to use a long-term observation method, so the observation efficiency and accuracy Neither are high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a laser radar system with simple structure, high precision and high effici...
