Coherent MIMO Transceiver for Communications and Radar
Abstract
The University of Notre Dame requests funds to acquire a multichannel radio frequency (RF) 8x8 MIMOcoherent transceiver system to support the study of coherent MIMO radar, communications, and remotesensing applications. The proposed equipment will enable the investigation of MIMO communicationsand radar systems based on the measurement of dispersion properties that requires tight coherence amongall of the MIMO subchannels. The system includes a newly available 8x8 MIMO PXI-based system thatprovides extremely tight subchannel coherence and synchronized multichannel transmit and receivecapability over frequencies ranging between a few MHz and 6 GHz. The equipment will provide neededcapabilities for efficient testing of coherent MIMO system concepts with up to 8 x 8 architectures.The proposed equipment is expected to impact a number of currently funded programs as well asprograms anticipated in the future. Current programs include polarization-based communications (Code30); Pulse source association (Code 30); PMD-base radar experimentation (Code 31); Wakecharacterizations (Code 31); MATERHORN soil sensing (MURI); and CASPER atmosphericcharacterizations (MURI). All of these programs can directly benefit from the acquisition of thisequipment to help overcome hardware synchronization and coherency issues with currently employedequipment. Other potential programs that the equipment could benefit include the study of cositesuppression, HF channel characterizations, and remote vibrometry sensing with beamforming.The requested equipment includes one complete 8x8 MIMO transceiver system. The system providesprecise phase, frequency, and timing synchronization on both transmit and receive channels to enablecoherent signal studies of polarization diverse and/or spatially diverse antenna architectures, which is anarea of intense study by the University of Notre Dame. This equipment also provides resources thatenable rich educational opportunities for students, including multidisciplinary research in electricalengineering, communications, remote sensing, vibrometry, turbomachinery, seismology, large-scalestructure monitoring; hydrology, geoscience, and atmospheric research.
