This paper deals with the development of a microwave, noise-adding radiometer, purposely designed for the fire detection in forest environments. The sensor operates at 12.65GHz and exploits commercial SAT-TV components such as a parabolic dish and a low-noise down-converter. First, an electromagnetic model is presented in order to estimate the radiometric contrast (increase of the brightness temperature with respect to the background) due to a fire covered by vegetation. Then, the design of the sensor is addressed, underlining the key technologies that allow the required performances to be attained at low industrial costs.

Abstract
This paper deals with the development of a microwave, noise-adding radiometer, purposely designed for the fire detection in forest environments. The sensor operates at 12.65GHz and exploits commercial SAT-TV components such as a parabolic dish and a low-noise down-converter. First, an electromagnetic model is presented in order to estimate the radiometric contrast (increase of the brightness temperature with respect to the background) due to a fire covered by vegetation. Then, the design of the sensor is addressed, underlining the key technologies that allow the required performances to be attained at low industrial costs.File in questo prodotto:
