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.
The modern system consists of five components of band 1.5 and band 3 equipment to cover the full spectrum of threats. The AN/ALQ-135 (v) system consists of the B3 RF Amplifier, B3 Control/Oscillator, B1.5 RF Amplifier, B1.5 Control/Oscillator, and the LRU-14.
Frequency agility is the ability of a radar system to quickly shift its operating frequency to account for atmospheric effects, jamming, mutual interference with friendly sources, or to make it more difficult to locate the radar broadcaster through radio direction finding.
Several online retailers and drone technology companies are marketing the sale of radio frequency jammers as drone deterrence or privacy tools, sidestepping federal laws that prohibit such devices ...
Radar jammer, a device used in radar jamming and deception; Radio jammer, a device used in radio jamming; Radio-controlled Improvised Explosive Device jammer, a counter-IED device; Mobile phone jammer, an instrument used to prevent cellular phones from receiving signals from base stations
Originally the terms were used interchangeably but nowadays most radio users use the term "jamming" to describe the deliberate use of radio noise or signals in an attempt to disrupt communications (or prevent listening to broadcasts) whereas the term "interference" is used to describe unintentional forms of disruption (which are far more common).
Example of a mobile phone jammer, produced by Jammerspro. A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting ...
An ALQ-144 jammer mounted on an OV-10 Bronco.. The AN/ALQ-144, AN/ALQ-147, and AN/ALQ-157 are US infrared guided missile countermeasure devices ().They were developed by Sanders Associates in the 1970s to counter the threat of infrared guided surface-to-air missiles like the 9K32 Strela-2.
