Discovery distance of buried objects is strongly dependent upon the absorption coefficient (Q(dB/m)) of radio waves in soils. Therefore, it is necessary to know Q (dB/m) as a function of the soil moisture in a wanted range of radio waves. This paper presents generalized results of measurements of the absorption coefficient of radio waves in sandy and clayey soils as functions of the wavelength in a free space ( λ0 ) in the range from 0.8 to 226 cm for five values of the soil moisture (p (%) = 2, 4, 6, 10, 16). Samples of the soil were corresponded to sandy and clayey soils of Moscow region (Russia). The present paper is an extension of the work reported in [1,2].
