Anotācija: The paper presents a study of the prerequisites and the original way of transition from quasi-monostatic antenna system to monostatic as applied to ultra-wideband pulsed contact radar subsurface sounding at shallow depths. For this purpose, the joint application of ultra-wideband electric "Bow-Tie" and magnetic "Bi-Quad" antennas is investigated. The mutual arrangement proposed in this work allows reducing to zero the distance between the centers of the antennas in the plane orthogonal to the direction of signal emission-reception. Results of full-scale tests with corresponding processing of obtained ensembles by the example of probing human body for detection and determination of parameters of biological rhythms and a tree trunk 58 cm in diameter showed satisfactory results for the radar with a central frequency of 1.5 GHz. At the same time, the suppression of the useful received signal due to application of the described design was only 2.3 dB at an acceptable level of the direct signal, which does not lead to overloading of the radar stroboscopic receiver input.
