For tactical communications over long distances, the military uses powerful mobile or stationary installations with large parabolic antennas and powerful transmitters. Such systems are vulnerable to attack or jamming, which in modern warfare is made simple. The new program of the DARPA Agency for Advanced Research of the United States Department of Defense suggests switching to a mosaic communication system with a mass of inexpensive antenna-transmitting complexes.
Within 45 months from the establishment of the DARPA RN DMC (Resilient Networked Distributed Mosaic Communications) program, participants will need to design a long-range tactical communications system, determine its operational architecture and experimentally confirm the performance and viability of the solution. The name of the RN DMC program can be translated into Russian as “Sustainable (elastic) network distributed mosaic communications”.
It is assumed that one antenna-transmitting complex in a mosaic communication system will cost no more than $ 1000, which ranks it as a consumable. Mosaics from the complexes will be built using the distribution of installations on the backs of soldiers, on vehicles, on ships, on board UAVs, on airplanes and on satellites. The compactness of the system suggests that it will have extremely high performance, which compensates for the lack of transmission power.
Each portable complex or “tile” will profess the principle of software-configurable radio. This requires protection from jamming and interception. The proposed approach will replace powerful amplifiers and large directional antennas with a mosaic of transceivers scattered over a large area. Thus, the long-range tactical connection promises to become more stable, and its nodes will be less noticeable for enemy influence.
