Abstract
In order to increase the reliability of detection and identification of hidden objects in various dielectric media, it is necessary to solve a series of interrelated problems. One of the most important and simultaneously insufficiently developed elements of the subsurface radar is the antenna system which determines the final results in many respects. The paper contains a comparative analysis of operation of two types of antennas designed and fabricated by the authors, namely, a unidirectional spiral antenna and an antenna on the basis of divergent slotlines with an exponential aperture.
