Abstract
The present invention relates to a radiometer for detecting electromagnetic signals in the microwave and millimeter wave range. The radiometer comprises an antenna operable to receive the electromagnetic signals, an internal noise signal generator operable to receive a control signal and to generate and output a calibration noise signal depending on the control signal, and a coupler operable to couple the received electromagnetic signal with the calibration noise signal and to output a coupled electromagnetic signal. Furthermore, the internal noise signal generator is activated based on the control signal.
