METHOD OF DETERMINATION OF FOREST FIRE DANGER Russian patent published in 2008 - IPC A62C3/02 A01G23/00 

FIELD: agriculture, physics.

SUBSTANCE: moisture content of the forest combustible materials (FCM) is determined by sounding the underlying surface in the SHF-range in the wave length allowing the electromagnetic radiation to pass through the FCM surface layer, forming the image matrix by means of a multi-beam antenna with the adjustable count digitisation in the scan band and the separate reception path in every beam, calculating the image matrix signal parameters, i.e. M₁ making mathematical waiting, σ being mean square departure, S_p being the relief shape, S₀ being the processed matrix geometrical area. It also includes separating the outlines on the image by the methods of spatial differentiation and FCM moisture content (W) inside the said outlines by the calibration function, i.e. W,%=S_p/S₀·exp(M₁/σ)·100%, where S_p is the image matrix signal relief area, S₀ is the processed matrix geometrical area, M₁ is the signal mathematical waiting, σ is the signal mean square departure.

EFFECT: fast determination of forest fire danger over vast territory.
