The Joint Tactical Radio System is projected to form the future military communications link that enables every echelon access to vital information. The JTRS credo is to embrace software defined radio (SDR) in order to enable communications between disparate systems using a common platform. Adapting communications to any standardized waveform is accomplished by rapidly reconfiguring the radio software for the waveform of choice. The Athena Radio Technology (ART) offers a configurable digital radio system that has reduced power and packaging requirements compared to the current UT LRU. Consisting of high-performance analog RF preconditioning, digital up and down converters, up and down sampling CIC filters, and FIR filters, ART form the core of a digital transceiver.
Benefit: The Athena Radio Technology will bring about an evolutionary change in the JTRS Universal Transceiver. Offering significant reductions in power and size requirements, ART can extend the state of the art of the JTRS Ground Mobile Radio cluster. The ART architecture is applicable to civilian communications systems as well. Marketed as an intellectual property component, chip designers involved in any facet of radio communications will be able to implement the ART radio in their systems.
