Lidar 4R for early detection of forest fires
Detection of smoke is carried out by the method of remote laser
sensing when backscattering signals from smoke clouds in the visible spectral
range are measured. The laser radiation reflected from the smoke allows to
determine the distance to it and to make an estimation of its density. The
lidar, when it was used in Portugal in 2000,
allowed to detect a source of smoke at 6.5 kms with the average discharge of
burning substance of 25 gramm per one second.
