Extension of Channelized Receiver Architecture to HF/VHF/UHF Tactical Receive-On

Radix Technologies is pleased to submit this Phase I SBIR proposal for the conceptual exploration, definition, and technical proposal of a small, light weight, low power manpack HF/VHF/UHF Receive Only Radio system. This sytem is referred to as the Tactical Receive-Only Radio or TROR. The TROR is designed for reconnaissance applications where rapid signal acquisition and set-on are required. The Phase II engineering design model of the TROR will provide flexible ESM receiver capabilities for fixed frequency, frequency agile, and cellular intercept over the .8 to 500 MHz frequency range in an 11" x 11" x 4.5", 25 pound unit. The TROR definition and development capitalizes on the emergence of digital technologies in battlefield communications. The radio is based on a set of recen technical advances including; a new digitizing RF architecture and residue number system (RNS) application specific integrated circuit (ASIC) digital channelizer chip set; and proven techology including; RF receiver design, polyphase filter based detection, qualification, and estimation processing, and real-time programmable Digital Signal Processor (DSP) signal tracking and demodulation code; which are integrated to provide sophisticated ESM and audio receiver capabilities.
