Radar jamming and deception. Radar jamming and deception is a form of electronic countermeasures (ECMs) that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally ...

Range gate pull-off. Range gate pull-off ( RGPO) is an electronic warfare technique used to break radar lock-on. The basic concept is to produce a pulse of radio signal similar to the one that the target radar would produce when it reflects off the aircraft. This second pulse is then increasingly delayed in time so that the radar's range gate ...
