- Аннотация: Based on the theoretical and numerical analysis of the interaction of video pulses containing only one or a few field oscillations with material media of different composition including dielectrics and conductors the main differences in their distribution and reflection are given. It is shown that traditional methods for solving Maxwell equations using the separation of variables and Fourier transforms are convenient for describing quasi-monochromatic waves with a slowly varying amplitude and phase, but ineffective for the analysis of non-stationary and non-harmonic fields. It is shown that it is necessary to take into account the features of propagation and reflection of video pulses when designing geo-radars in order to achieve the maximum probing depth altogether with the best resolution in a single product. A comparison was made of theoretical conclusions on the propagation of video pulses in the medium and numerical models with experimental data obtained in field experiments using equipment of the GROT 12 model range, which designed taking into account the interaction of powerful video pulses with various natural media.
