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 TV-SAT 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
