Application of Laser Technology in Evaporation Duct Detection

Abstract

Aiming at how to detect evaporation duct environment accurately in real time, method of detecting atmospheric duct by using laser technique was put forward. From the model of air refractive index of radar band, theoretical relationship between laser scattering properties of aerosol over the ocean and vertical change characteristics of the air humidity was established; judge whether to produce evaporation duct, through using laser to detect the echo signal characteristics of aerosol. The research content is an important complement for methods of atmospheric duct detection, and it can solve several common problems that atmospheric duct forecasting methods needs rigorous measuring conditions, its measurement results delay, it need be estimated by experience and detecting precision is not high, which has higher military application value.
