The Advanced RF Mapping program seeks to provide radio frequency (RF) situational awareness using low-cost sensors distributed over the battlespace. The sensors include devices deployed for other purposes, such as tactical radios. The vision is that all RF devices in theater will support RF situational awareness when not performing their primary mission.
The continued growth in unmanned, sensor, and networked devices is expected to drive the need for larger, more capable and more diverse communications systems. Among other enhancements, these systems must improve jam-resistance and low probability of detection to keep pace with adversaries’ growing electronic sophistication and must adapt to fast-changing operational environments. By contrast, today’s military communications architectures are static and inflexible.
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 undersea domain imposes well-known limits on communication and therefore the capacity to transfer the right information necessary to its intended purpose. The TIMEly program aims to develop concepts for a heterogeneous underwater network architecture that enables the vision of mosaic warfare by the contemporaneous composition of effect chains from available assets in any domain, but with an emphasis on the underwater domain in order to provide options for execution on the fly.
Office Director
Dr. Timothy Grayson is the director of the Strategic Technology Office (STO) at DARPA. In this role, he leads the office in development of breakthrough technologies to enable warfighters to field, operate, and adapt distributed, joint, multi-domain combat capabilities at continuous speed. These technologies include sensing, communications, and electronic warfare technology and the supporting tools and decision aids needed to compose, integrate, and operate complex combat architectures.
