Start with a selection of tiles of different colors and shapes and you can assemble a thousand different mosaic images. Mosaic composition has become an important metaphor for STO. DARPA envisions combatant commanders of the future plucking from a list of manned and unmanned weapon systems and tiling them together into a battle plan.
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.
