DEFINITION OF NOISE-COMPENSATED RADIOMETER SENSITIVITY

V.K. Volosyuk, V.V. Pavlikov, S.S. Zhyla

In work formulas of sensitivity on the basis of Fourier transform application, which operating with double-sided amplitude-frequency characteristic and the spectra located both in the field of positive, and in the field of negative frequencies are received. Sensitivity formulas are deduced for two cases, when predetector of radiometer part is aperiodic and frequency-selective. Examples of formulas measurement for sensitivity depending on concrete amplitude-frequency characteristic predetector parts of radiometers and from a kind integrating device are resulted.

Key words: sensitivity, noise-compensated radiometer, amplitude-frequency characteristic, integrating device.
