Low electromagnetic coupling bistatic subsurface radar using EBG structures

Abstract

EBG structures have been developed widely for reducing electromagnetic coupling. On the other hand, Bistatic radar is a system which comprises a transmitter antenna and receiver antenna. In recent years, the bistatic subsurface radar is applied to detect relatively shallow structure such as tumor detection, steel reinforced detection in concrete and etc… On the other hand, the electromagnetic coupling between transmitter antenna and receiver antenna becomes problem, because, the bistatic radar detects a reflection wave from the target by the receiver antenna, therefore artifact caused by the coupling. To reduce this coupling a cavity is used, however, the cavity is not enough to reduce the electromagnetic coupling between transmitter antenna and receiver antenna. We have proposed bistatic radar system using EBG structure. In this paper, the bistatic radar system using EBG structures will be introduced briefly. And, the target detection result by using proposed bistatic radar system will be indicated.
