Electromagnetic radiation weapons

ELECTROMAGNETIC PULSE (EMP). The explosion of a nuclear weapon creates a strong pulse of electromagnetic radiation, referred to as an electromagnetic pulse. It is capable of damaging electrical or electronic systems, including command-and-control systems such as... 

Radar. Radar (RAdio Detection And Ranging) devices operate by transmitting a particular form of electromagnetic energy, and processing that portion of it (the echo ) which is radiated back. Radar techniques are used to detect and locate targets, to control weapons, for navigation, and in a secondary form — for aircraft identification... 

Electromagnetic pulses (EMPs) are also produced by nuclear weapons that are exploded at high altitudes, and are caused by the interaction of radiation from the explosion with electrons in the atmosphere and with the Earth s magnetic field. EMPs are essentially powerful radio waves that can destroy many electronic circuits.
