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.
Jul 20, 2016 · These ghost readings will disappear and be replaced by the target reading when the actual target vehicle gets close enough, and will not affect the accuracy of the target reading. Most radar units have an automatic gain control, which automatically increases the sensitivity of the unit when there is no signal present.

Interference can cause the radar to stop processing or produce a false speed reading, sometimes out of nowhere. The radar's self adjusting gain to manage interference can significantly lower detection range unbeknownst to the operator, especially if radar range manual adjustment is set to maximum.
Jun 16, 2021 · There are three classes of techniques available to mitigate radar interference without affecting overall system performance, as shown in Figure 2. The first class of techniques avoids the saturation of the front end, which happens when a radar sensor is exposed to a strong interferer.
