TECHNICAL DEFINITION

High-Power Microwave (HPM) weapons are directed-energy systems that generate intense electromagnetic radiation in the microwave frequency spectrum, primarily utilized in electronic warfare for non-kinetic effects to neutralize or degrade adversary C4ISR systems, integrated air defense networks, and critical electronic infrastructure.

BACKGROUND

A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams. Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices.
