Paper Abstract

Theoretical and experimental investigations of the radiation properties of a buried leaky coaxial cable (LCC), as a guarding radar system, are presented for various artificial and natural local inhomogeneous conditions along the cable system. The theoretical model of two coupling coaxial lines, outside which consists a sub-soil medium, is introduced to describe interactions of two modes, external and internal, which determine the working characteristics of such a leaky coaxial cable. The vertical and the horizontal distribution of radiation along and across the cable at height h above the ground are examined experimentally by means of a loop of the LCC buried in the sub-soil medium. The comparison between experimental data and theoretical predictions of radiation directivity of the LCC for the guarding radar system is presented. The possibilities of generating a complicated interference picture of such a radar pattern caused by different kinds of local inhomogeneities are discussed theoretically and studied experimentally.
