A novel monostatic concurrent multiband radar front-end architecture and its dual-band implementation

This paper proposes a novel monostatic concurrent multiband radar front-end architecture that can work in several independent bands simultaneously. Compared with the conventional single-band radar, multiband radar has the potential to support different modulation modes in independent frequency bands and multi-functional integration, and has a good ability to adapt to complex electromagnetic environment and flexible applications. In order to demonstrate the validity of this proposed multiband radar front-end architecture, the corresponding dual-band radar and two single-band radar prototypes are fabricated and measured. A good agreement of measured results between the dual-band and two single-band radar front-ends validates the effectiveness and reliability of the proposed new radar architecture.
