Paper Abstract

The possibility of early forest fire detection within a range up to ~2 km using a portable eye-safe 1540 nm lidar is demonstrated in this paper, both on experimental and theoretical ground. An estimation of the detection efficiency using a mathematical model based on the 3D system of Navier-Stokes equations describing the smoke plume evolution in the presence of wind, agrees reasonably well with experimental results. Calculations made using the model show that a detection range up to ~5.5 km can be achieved by accumulating lidar return signals.
