In order to reduce the dimensionality (reduce the number of features of the object of study), the article uses the methodology of “compendium–table–infographics”. Three projects related to the study of radio wave propagation in the Crimea and the Black Sea Fleet (1914, 1928 and 1954–1955), as well as studies of the physical parameters of fields and environments (hydroacoustic and magnetic fields, radar, thermal and laser characteristics of surface ships, seismic and seismoacoustic waves) are considered.
