Abstract

The main characteristics defining a resolution and penetration depth of modern ground penetrating radar (GPR) are wide frequency band of radiated signals and high efficiency and uniformity of radiation through the whole working frequency range. Electrical parameters of a ground vary within a wide range. However, the main part of them has such a value that the pulse signals of nanosecond duration range corresponding to the frequency range from tens MHz to units GHz are optimal for several meters depth of sounding. On the one hand, such a signals allow to obtain a resolution about 10 cm, on the other hand to sound down to the several meters depth. As a rule, it suffice to solve a wide range of problems.

A design of an improved antenna system for GPR "Zond-10" produced by firm "Radar, Inc.", Riga, Republic of Latvia is discussed in the presentation. Advantage of the new antenna system is decreased duration of the after pulse oscillation with the energetic characteristics of the ground penetrating radar remaining the same.
