A numerical method of calculating the spectral-ratio temperature for objects whose spectral emissive power ελ depends on the wavelength λ is described. A calculation is carried out for two types of broadband radiation receivers based on Si/Si and Si/InGaAs structures. The differences between the actual temperature of the objects and their spectral-ratio temperature are given for Fe, Ni, Cu, Ag, and Co as examples. It is shown that there are no disagreements between the results of numerical and analytical calculations of the spectral-ratio temperature.
