METHOD OF SHF MEASUREMENT OF PHYSICAL TEMPERATURE OF OBJECTS WITH USE OF RADIOMETER AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 1999 - IPC

FIELD: technique measuring intensity of thermal radio radiation of objects. SUBSTANCE: method of SHF measurement of physical temperature of objects with use of radiometer involves measurements separated in time. Antenna for each measurement is directed to object to form noise signal from object across its output. First auxiliary noise signal is formed first, then second auxiliary noise signal is fed through antenna to object for the time of measurement of its physical temperature. Signal from antenna output and first auxiliary noise signal are fed into first and second inputs of radiometer correspondingly. Level of noise of first and second auxiliary signals is controlled by integrated voltage of radiometer that is measured. Calibration with the aid of exterior calibration sources is conducted once prior to measurements of integrated voltage of radiometer from objects separated in time and its results are stored for long time. Physical temperature of objects is computed by results of measurements of integrated voltage of radiometer with allowance for stored results of calibration. EFFECT: simplified process of measurements of physical temperature of objects separated in time. 8 cl, 5 dwg
