HF Digital Receiver

ABSTRACT: Matrix Research, Inc. is pleased to submit this Phase I SBIR proposal for the Air Force topic AF121-145: HF Digital Receiver. In this proposal, Matrix present a work plan to develop a high frequency digital receiver that is design to support the next generation of over the horizon radar systems. This receiver includes support for a 2D antenna array with MIMO radar modes, direct RF-to-digital conversion, and a large instantaneous bandwidth for multiband processing. The outcome of Phase I effort is a complete receiver design with modeled performance estimates. In Phase II, this design is to be prototyped and tested. BENEFIT: Matrix will pursue applications of the receiver in both military and commercial applications. In military applications, the proposed receiver offers use in radar and communication applications. In particular, applications that encounter measurement of small signal levels near large signals will significantly benefit from this high dynamic range receiver. In commercial applications, environmental sensing and surface wave oceanic radars could benefit.
