Abstract
IR radiation sources are used in a remote path analyzer of the surface atmosphere on the basis of a Fourier spectrometer. The idea is introduced of minimum operating paths on which it is possible to measure the concentrations of the main contaminants at a level of maximum permissible concentrations. The theoretical estimate of such paths is provided. The formulas for estimating the expected signal-to-noise ratio and formulating the requirements for an IR source are presented. A method for manufacturing simple and efficient IR sources based on the ΠЭ-type wire-wound resistors is described. The performance characteristics of different radiation sources are compared.
