Radio jamming is the deliberate blocking of or interference with wireless communications. [1] [2] In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio.
The most important method to counter radar jammers is operator training. Any system can be fooled with a jamming signal but a properly trained operator pays attention to the raw video signal and can detect abnormal patterns on the radar screen. The best indicator of jamming effectiveness to the jammer is countermeasures taken by the operator.

Estonia has accused neighbouring Russia of jamming GPS navigation devices in airspace above the Baltic states, echoing concerns from airlines that say they have been contending with such ...
This was achieved by the SAM site's radar receiver locking on to radio noise emissions generated by an aircraft's jamming pod. In cases of heavy jamming, missiles were often launched exclusively in this mode; this passive tracking meant that SAM sites could track targets without needing to emit any radar signals, and so American anti-radiation ...
Jamming occurs when non-target sounds interfere with target echoes. Jamming can be purposeful or inadvertent, and can be caused by the echolocation system itself, other echolocating animals, prey, or humans. Echolocating animals have evolved to minimize jamming, however; echolocation avoidance behaviors are not always successful.
In live sound or recordings in which a microphone is placed in front of an instrument or a guitar amplifier, the "sweet spot" is a placement or position of a microphone which yields the most pleasing sound; in the context of listening to a mix in a studio through monitor speakers, the "sweet spot" is a distance away from the speakers that the ...
