The electromagnetic spectrum is the sixth domain of modern warfare. The effectiveness of combat operations in the land, sea, air, space, and cyber domains depends on our ability to control and exploit the spectrum, because it is critical to our capabilities in navigation. While the spectrum is at the heart of current and future warfare, it remains highly contested and congested, and future info-centric warfare will require more access than ever before. DARPA/’s Microsystems Technology Office is developing components to effectively operate in a dynamic, contentious spectrum, which includes research in hardware components for maximal flexibility, machine learning for spectral reasoning, and fast development cycles for fielding complex electromagnetic systems.
