Scanning band of lidar on wavelength 10,6μm for remote sensing of oil films on sea surface

摘要

An analytical expression is obtained for estimating the scanning band width of a lidar destined to detect oil films on the sea surface at a given threshold contrast level "oil film clear sea water" and a given minimal acceptable signal-to-noise ratio. Results of calculations of dependence of the scanning band width on the lidar output energy are presented in the infrared range middle for different wind speeds and atmospheric conditions. It is shown that the scanning band width strongly depends on the lidar output energy, wind speed and optical condition of the atmosphere.
