发明名称 RADIOMETER MODULATOR-DEMODULATOR SYSTEM
摘要 An improved microwave radiometer of the comparison type features simplified construction through the employment of a unitary modulator-demodulator system operating on the high frequency signal to be investigated by cyclically sampling and exposing the signal to be investigated and a reference signal to synchronous demodulation by a demodulator element constructed integrally with the high frequency sampling switch or chopper.
