Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while systems that produce confusing or contradictory signals are known as deception, but it is also common for all such systems to be referred to as jamming. There are two general classes of radar jamming, mechanical and electronic.
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 ALE-55 is an RF countermeasure designed to protect an aircraft from radar-guided missiles.It consists of an aircraft-towed decoy and onboard electronics. It works together with the aircraft's electronic warfare system to provide radar 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]
Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
Moving target indication (MTI) is a mode of operation of a radar to discriminate a target against the clutter. [1] It describes a variety of techniques used for finding moving objects, like an aircraft, and filter out unmoving ones, like hills or trees.

The RR-144 is designed to prevent interference with civil ATC radar systems. Chaff, originally called Window [1] or Düppel, is a radar countermeasure involving the dispersal of thin strips of aluminium, metallized glass fiber, or plastic. [2] Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. [3]
