EMI Military Challenge | Description |
Fixed land-based installations | Electronics at military bases may be near radar systems that produce emissions at levels and frequencies far greater than in commercial settings. Equipment at military facilities may also require protection against an electromagnetic pulse (EMP) generated by high-altitude weapons. |
Mobile land-based installations | EMI threats to technologies used in military vehicles are not unlike the EMI threats faced by conventional vehicles. An EMI military strategy needs to reduce the potential EMI risks associated with exposure to radar and EMP. |
Marine-based vessels | Ships, submarines, and other water-based vessels with metal hulls and superstructures can raise EMI military issues. Devices must be hardened against emissions generated by on-board radio communications and navigation systems. Equipment intended for use below deck may encounter different types of EMI risk than similar equipment used above deck. |
Aviation and aerospace | An EMI military risk that’s unique to aircraft* is potential exposure to high-intensity radio frequencies (HIRF) from radar equipment used by other aircraft operating in proximity during combat. The EMI risk for technologies used in planes, jets, and helicopters depends on whether the equipment is intended to be installed inside or outside of the aircraft. |
