Full-duplex transceivers for defense and security applications

Abstract

<p>The full-duplex (FD) radio technology that promises to improve the spectral efficiency of wireless communications was, however, initially used in continuous-wave (CW) radars by means of same-frequency simultaneous transmission and reception (SF-STAR). In this chapter, we explore how the recent advances in the FD technology, which have been mainly motivated by higher throughput in commercial networks, could in turn be used in defense and security applications, including CW radars and also electronic warfare (EW) systems. We suggest that, by integrating tactical communications with EW operations such as signals intelligence and jamming, multifunction military full-duplex radios (MFDRs) could provide a significant technical advantage to armed forces over an adversary that does not possess comparable technology. Similarly in the civilian domain, we examine the prospective benefits of SF-STAR concepts in security critical applications in the form of a radio shield.</p>
