AB  - Textile camouflage structures designed for weather protection, combat suits, and military uniforms for land forces are
defined by their physical, mechanical, and optical properties. An analysis of the statistical populations of reflection within
the wavelength range of 860–1200 nm revealed the degree of dispersion in the measured values. A novel method was
developed to determine the weight of monochromatic areas on a multi-coloured surface. Various camouflage textile
structures were examined to investigate the correlation between reflection indices and the weight of the single-coloured
regions. Several parameters were identified, including the colour index, the range of colour reflectance, the area covered
by each colour, and the weight of the colour-covered region. To assess the degree of reflection for each colour within
the spectral range of 860–1200 nm, the median of the reflection values was calculated, as it provides a more
representative measure of the overall reflective properties. The frequency distribution of these values was analysed,
leading to the establishment of a ranking of camouflage types based on their reflection coefficients, starting with the
lowest reflection value. Regression curves were derived for the reflection index values at wavelengths between
860–1200 nm, with increments of 10 nm. These initial regression curves, along with those weighted by colour area,
include regression equations for the analysed textile structure variants. These equations enable the calculation of the
regression index as a function of wavelength.
