“…This method is widely used for routine laboratory research [13]. The high luminosity of the method makes it possible to create infrared Fourier spectroradiometers (FTIR spectrometer), which make it possible to register its IR spectra by the intrinsic thermal radiation of a substance and, as a consequence, to detect and identify substances [2,14,15]. Remote sensing is a universal method for studying the Earth's surface [16].…”

The analytical dependence of the signal-to-noise ratio (SNR) of the measured interferograms of an infrared (IR) Fourier spectrometer on the temperature contrast of the observation path and on the physicochemical properties of the test substance is obtained. The analytical dependences of the minimum detectable concentration of a substance on the value of the temperature contrast are obtained. It is shown experimentally that the theoretical estimates of the minimum detectable concentrations with an accuracy of the order of the mean square error correspond to the experimental values. The obtained analytical dependences make it possible for the given physicochemical properties of substances, the parameters of the IR Fourier spectrometer, and the values of the temperature contrast to estimate minimum detectable concentration of the substance.
