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.
