In some cases, jamming of either type may be caused by friendly sources. Inadvertent mechanical jamming is fairly common because it is indiscriminate and affects any nearby radars, hostile or not. Electronic jamming can also be inadvertently caused by friendly sources, usually powerful EW platforms operating within range of the affected radar.
Pull-off belongs to the wider family of "deceptive jamming" concepts that use details of the target radar to their advantage, rather than attempting to simply overpower the radar's signal. Alternate names for "pull-off" include "stealing" and "walk-off". A related technique is angle deception jamming.
Stealth technology, also termed low observable technology (LO technology), is a sub-discipline of military tactics and passive and active electronic countermeasures. [1] The term covers a range of methods used to make personnel, aircraft , ships , submarines , missiles , satellites , and ground vehicles less visible (ideally invisible ) to ...
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 ...
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] The jammer's continuous transmissions will provide a clear direction to the enemy radar, but no range information. [1]
An electronic-warfare aircraft is a military aircraft equipped for electronic warfare (EW), that is, degrading the effectiveness of enemy radar and radio systems by using radar jamming and deception methods. [1] In 1943, British Avro Lancaster aircraft were equipped with chaff in order to blind enemy air defence radars.
It was found that the most effective version was strips of black paper backed with aluminium foil, exactly 27 cm × 2 cm (10.63 in × 0.79 in) and packed into bundles each weighing 1 pound (0.45 kg). The head of the TRE, A. P. Rowe, code-named the device "Window". In Germany, similar research had led to the development of Düppel.
Angle deception jamming is an electronic warfare technique used against conical scanning radar systems. It generates a false signal that fools the radar into believing the target is to one side of the boresight , causing the radar to "walk away" from the target and break its radar lock-on .
