Paper Abstract

The problem of forest fire detection from space using infrared channels of advanced very high resolution radiometer (AVHRR), under conditions of broken clouds, has been considered. Using numerical simulation technique, we studied the statistical characteristics of intensity of upward IR radiation, emitted by the fire and backing, including emission of surface, atmosphere, and clouds in wavelength intervals 3.55 - 3.93 and 10.3 - 11.3 micrometers . Gamma distribution is suggested for approximation of probability density of background power recorded by radiometer. Using the Meyman-Pearson test, we estimated the probabilities of detection of fires of different sizes. The obtained results illustrate the efficiency of the suggested approach.
