LIDAR ENERGETICS IN REMOTE SENSING OF OIL FILMS ON SEA

ENERGETIKA LIDARA PRI DISTANTSIONNOM OBNARUZHENII NEFTYANYKH PLENOK NA MORE

An estimation is given of the energy arriving at the input of the receiving system of a LIDAR employing a CO2 laser in remote sensing of the sea. The calculations take into account the attenuation of the lambda = 10.6 mu laser beam in the atmosphere (in the water vapor continuum, CO2 and aerosol) as well as the variation of the sea surface brightness coefficient as a function of the wind speed. It appears that with increasing the wind speed from 2 to 15 m/s the energy arriving at the receiving system input decreases when observation is carried out in nadir; for observation accomplished with the 20 degree angle it increases sharply (mainly due to the variation of the sea brightness coefficient). A specific example is considered which makes it possible to estimate the observation height from which an oil film on the sea may be detected by means of a medium power CO2 LIDAR.
