Invisible conflicts on the electronic battlefield are won or lost in tiny fractions of a second, with implications that can decide the success of a mission or the survival of warfighters. The conflicts are waged by embedded RF systems; some drive radar systems, while others jam and spoof radars, or jam the control signals for an IED. They may also be used to detect and locate an adversary’s operations, often identifying specific types of vessels and aircraft, or to protect against detection.
