Phased Array Architecture Enabling Scalable Integrated Sensing and Communication

Abstract

Phased array systems can straightforwardly support integrated sensing and communication (ISAC) as well as other functions simultaneously by incorporating in-band full-duplex (IBFD) technology. Digitally-controlled self-interference cancellation techniques have been shown to create isolation between transmit and receive sub arrays within a single aperture for limited numbers of elements. This paper discusses the key components of a scalable panel-based IBFD array system, including the aperture and backplane assemblies as well as a cold plate structure for thermal management. The array is designed to operate from 2.7 to 3.5 GHz, and will provide the opportunity to demonstrate ISAC capability in a fashion that is scalable for many different deployment locations and/or platforms.
