Manipulation of the electromagnetic spectrum for military advantage

Showing 2 results for EW + SWAP RSS
Dominance of the radio frequency (RF) spectrum is critical to successful U.S. military operations. Today, we do this using discrete radar, electronic warfare (EW), and communication payloads that are separately designed, procured, and integrated on platforms. These payloads typically use dedicated apertures, are realized with tightly coupled hardware and software, and are not well-coordinated in their use of spectrum. This rigid and constrained approach makes it difficult and time-consuming to adopt new technology, adapt to rapidly changing adversary threats, maneuver functions effectively in spectrum, and create comprehensive compact RF systems.
Radios are used for a wide range of tasks, from the most mundane to the most critical of communications, from garage door openers to military operations. As the use of wireless technology proliferates, radios and communication devices often interfere with and disrupt other wireless devices. First responder radios need to be able to communicate reliably in such congested and contested environments and to share radio spectrum without direct coordination or spectrum preplanning.
