Multiple-ring Circular Array for Ground-Penetrating Radar Applications: Basic Ideas and Preliminary Results

Abstract

Abstract-In this paper, the possibility of using a multiplering circular array as an antenna array for Ground-Penetrating Radar systems is investigated. The theory behind the proposed idea is presented. The preliminary numerical results that are obtained suggest that the proposed configuration is promising. It allows achieving a wide frequency band and low dynamic range ratio of excitations, thus simplifying the feeding network. Further interesting requirements may be satisfied by exploiting a combination of deterministic and stochastic synthesis techniques to design the array.
