Jamming is deliberately producing interference with the reception of radio-wave signals by transmitting stronger radio waves to drown out the signals. Jamming is used to prevent the reception of radio broadcasts and to impair military radio communications and radar.

Broadcast Jamming

Since the beginning of World War II, many governments have jammed the reception of radio broadcasts from foreign countries as an act of national policy. High-powered transmitters, capable of rapid change of frequency, are used to send radio waves modulated with noise. Such transmission can effectively prevent broadcast reception in local areas.

Military Jamming

In military operations, all of the. more advanced nations rely on radio communications and radar for command and intelligence functions. Jamming of radio reception and radar operation is widely used by each military force to impair the effectiveness of the command and intelligence functions of the opposing force. Such jamming is a part of the electronic counter-measures (ECM) that are widely used in modern warfare. These countermeasures include acts such as blocking reception, transmitting false radar target signals, and transmitting false messages.
