Abstract. Based on the analysis of theoretical and experimental data, reasons for the greater sounding depth of georadars using ultra-wideband signals are discussed as compared to traditional GPRs using monochromatic sounding signals. Within the framework of classical concepts, a physical explanation is proposed for the different patterns of attenuation of electromagnetic pulses of different shapes in natural media. The advantages of using inseparable solutions of Maxwell's equations in studying the propagation of short electromagnetic video pulses in dissipative media are discussed in comparison with traditional solutions using the Fourier transform.

Key words: GPR, interference, attenuation, scanning depth, video pulse.
