Modern networks and platforms rely on access to the radio frequency (RF) spectrum for communications, radar sensing, command and control, time transfer, and geo-location. Electromagnetic interference, due to congestion in the spectrum or malicious jamming, can have catastrophic effects. Countering such interference is particularly important for unmanned platforms. To address this challenge, the Hyper-wideband Enabled RF Messaging (HERMES) program seeks to provide an assured link for essential communications by developing a jammer- countering capability that is orders of magnitude beyond the state-of-the-art.
There is increasing interest in making broader use of the millimeter wave frequency band for communications on small mobile platforms where narrow antenna beams from small radiating apertures provide enhanced communication security. Today’s millimeter wave systems, however, are not user friendly and are designed to be platform specific, lacking interoperability and are thus reserved for only the most complex platforms.
The Mobile Hotspots program envisions air, mobile and fixed assets that provide a gigabit-per-second tactical millimeter-wave backbone network extending to the lowest-echelon warfighters.
The Network Universal Persistence (Network UP) program seeks to develop and demonstrate radio technology that maintains network reliability through periods of frequent signal degradation that may occur during operations in multiple environments. From time to time, network outages may occur and data transmission may be challenged.
The Next-Generation Nonsurgical Neurotechnology (N3) program aims to develop high-performance, bi-directional brain-machine interfaces for able-bodied service members. Such interfaces would be enabling technology for diverse national security applications such as control of unmanned aerial vehicles and active cyber defense systems or teaming with computer systems to successfully multitask during complex military missions.
