The laser radar system for measuring and processing of multiple atmospheric parameters in troposphere
Abstract
A laser radar is proposed which is capable of simultaneously measuring several atmospheric parameters in the troposphere. The discussion covers the principles of atmospheric parameter measurement by laser radar, the use of laser radar for simultaneous measurement of multiple parameters, and experimental results. Since various atmospheric parameters can be measured simultaneously by changing the wavelength-selecting filter and the data processing method, one receiving system is used on the time-sharing basis. The requirement of making all measurements within a short period of time is satisfied by switching filter sections successively within a short time interval (less than 10 min). The experiment yielded information on humidity, extinction coefficient, visibility, Mie bulk scattering coefficient and Mie scattering parameter. Raman-scattered light from nitrogen and vapor molecules and Mie-scattered light from aerosols are also measured.
