Abstract

The radiometric thermometer includes a microwave sensor and electronic means for processing the electrical signal delivered by the sensor. The electronic means includes means for preamplifying the electrical signal delivered by the microwave sensor; variable-gain amplification means with automatic gain control, which means amplify the signal delivered by the preamplification means, the amplification means having an automatic gain control signal that allows the gain to be automatically adjusted on the basis of the signal output by the amplification means, and electronic temperature measurement means for measuring temperature on the basis of the automatic gain control signal.
