Abstract
Ya LiONR, Code 31Approved for Public ReleaseSAMURAI: Spectrally-agile Arrays at Millimeter-Wave for Universal programmability and Resilience with AI1. Abstract: The goal of this proposal is enabling a new class of intelligent, programmable, multi-functional, and spectrally agile millimeter-Wave antenna and chip-scale transceiver arrays that can operate flexibly across 30-100 GHz. The spectrum between 30-100+ GHz is a critically important spectrum for DOD, command, control, intelligence, surveillance, reconnaissance, and can support jammer-tolerant wireless communication, high-resolution radar, sensing and imaging. Current large-scale array systems, however, are too complex, expensive, lack scalability and interoperability. The goal of this proposal is enabling a new class of intelligent, programmable, multi-functional, and spectrally agile millimeter-Wave antenna and chip-scale transceiver arrays that can operate flexibly across 30-100 GHz for multi-functional operation across sensing and communication. We will explore automated synthesis of complex mmWave/THz ICs based on the deep-learning based approaches that can allow rapid and automated synthesis of complex high-frequency systems. This research will break new grounds in wireless communication, radar, Electronic Warfare (EW), Electronic Attack (EA), and Electronic Protection (EP) applications, and in addressing emerging multi-mode threats, allows advanced LPI/LP capabilities, reconfigurable radar imaging and secure wireless communication. The first task will focus on a new class of frequency-agnostic beamforming for multi-functional operation. In particular, through non-uniform antenna array distribution with a minimum spacing of half-wavelength at the lowest end (30 GHz), we will create capabilities that 1) allow beamforming at any frequencies between 30-100 GHz in a programmable fashion, 2) overcome the complex low-inter element coupling, and3) has narrow beam widths for high-resolution radars and sensingWe will also create packaged antenna systems with silicon integrated transceivers that allows low-cost, low SWAP, and digital programmability, and inter-operability. In addition, the scalable packaged systems will allow soft degradation against failure due to easy replacement of the failed silicon tiles with packaged antennas. These forms of architecture can enable the next-generation of smart millimeter-wave systems for DOD applications. Training: Overall, the proposed system will allow training of graduate and undergraduate students in the state-of-the-art research in RF-THz integrated electronic directly beneficial to the DOD and society in general.
