Manipulation of the electromagnetic spectrum for military advantage

Showing 1 results for EW + Unmanned 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.
