ABSTRACT:
A radiometer includes a housing and an RF board carried by the housing. A hybrid and amplifier circuit receives an unknown signal and a known reference signal. A switch receives signals as inputs from the hybrid and amplifier circuit and switches between the inputs. A detection circuit receives and detects the signal from the switch forming a detected signal. A controller board is carried by the housing and an integration circuit and processor receive the detected signal and produces a digital output.
