Resilient Networked Distributed Mosaic Communications (RN DMC) Proposers Day
The purpose of this Proposers Day is to provide information on
the RN DMC program. The RN DMC program's objective is to provide long-range
communications through 'mosaic' antennas composed of spatially distributed
low size, weight, power, and cost (SWaP-C) transceiver elements or 'tiles'.
The RN DMC approach replaces high powered amplifiers and large directional
antennas with mosaics of spatially dispersed tile transceivers. Transmit
power is spatially distributed amongst the tiles, and gain is achieved
through signal processing rather than the use of a physical antenna aperture
to concentrate energy. Individual tiles can use radio frequency (RF)
sounding to estimate channel responses and adjust transmit carrier phases.
This enables the distributed mosaic antenna to form directional beams and/or
spatial nulls in desired directions.
