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.
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]
Several technology research and development efforts exist to integrate the functions of aircraft flight control systems such as ailerons, elevators, elevons, flaps, and flaperons into wings to perform the aerodynamic purpose with the advantages of lower RCS for stealth, via simpler geometries and lower complexity (mechanically simpler, fewer or ...
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.
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 .
The reference to "repeater jamming" should be disambiguated. I believe the most-often used term is Deception Jamming. Furthermore, emphasis should be added that for effective deception jamming to happen, the jammer must first analyze the target radar's operating parameters, such as frequencies, PRFs, scanning patterns, etc.
The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased-array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.
