RADIOMETRIC THERMOMETER

摘要

The radiometric thermometer comprises a microwave sensor (1) and electronic means for processing the electrical signal delivered by said sensor. Said electronic means comprise: means (5) for preamplifying the electrical signal (S1) delivered by the microwave sensor (1); variable-gain amplification means (7) with automatic gain control, which means (7) amplify the signal delivered by the preamplification means (5), said amplification means (7) having an automatic gain control signal (Vagc) that allows the gain to be automatically adjusted on the basis of the signal (S7) output by the amplification means, and electronic temperature measurement means (8) for measuring temperature on the basis of said automatic gain control signal (Vagc).
