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.
When jamming is strong enough, the radar receiver can detect it from a relatively low gain sidelobe. The radar, however, will process signals as if they were received in the main lobe. Therefore, jamming can be seen in directions other than where the jammer is located. To combat this, an omnidirectional antenna is used for a comparison signal ...
Basic radar ECM strategies are (1) radar interference, (2) target modifications, and (3) changing the electrical properties of air. [1] Interference techniques include jamming and deception. Jamming is accomplished by a friendly platform transmitting signals on the radar frequency to produce a noise level sufficient to hide echos. [1]
R8 Radar/Laser Detector. The R8 is Uniden's top-of-the-line offering. It can identify threats coming from all four directions thanks to its dual antenna, and you get notified via voice alerts.
This can be used to track the jammer using a variety of techniques. A well developed instance of this was deployed by the RAF in their RX12874 network, which could track jammer-carrying aircraft with accuracy equal to a radar. More generally, a barrage jammer's signal is so easy to receive that it makes an excellent early warning signal on its own.
The AN/ALQ-218 is an airborne passive Radar warning receiver / electronic warfare support measures / electronic signals intelligence (RWR/ESM/ELINT) sensor system designed for airborne situational awareness and signal intelligence gathering. The AN/ALQ-218 detects, identifies, locates and analyzes sources of radio frequency emission.
The jamming system is intended as a mobile system which is installed in the vehicle. It is equipped with the Omni-directional antennas that are part of the system. The output power of the jammer is up to 740 W. The jamming system is easily controlled and the failures are easily diagnosed. It is controlled on the front panel.
As jammers proliferated, a number of existing ARMs such as the AGM-88 HARM was modified to also target jammers as the source of radiation. [2] Jammers also led to the addition of a home-on-jam feature to missiles that usually use a different targeting mode (e.g. active radar homing, semi-active radar homing, GPS), allowing them to switch to an anti-radiation targeting mode when radar ...
