== Radar ECM == {{Main|Radar jamming and deception}} [[File:Radar jamming.jpg|thumb|Simulated radar screen in US Navy training exercise showing simulated jamming (triangular white area lower right)]] Basic radar ECM strategies are (1) radar interference, (2) target modifications, and (3) changing the electrical properties of air.<ref name="proceedings" /> 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.<ref name="proceedings" /> The jammer's continuous transmissions will provide a clear direction to the enemy radar, but no range information.<ref name="proceedings" /> Deception may use a transponder to mimic the radar echo with a delay to indicate incorrect range.<ref name="proceedings" /> Transponders may alternatively increase return echo strength to make a small decoy appear to be a larger target.<ref name="proceedings" /> Target modifications include radar absorbing coatings and modifications of the surface shape to either "stealth" a high-value target or enhance reflections from a decoy.<ref name="proceedings" /> Dispersal of small aluminium strips called [[Chaff (radar countermeasure)|chaff]] is a common method of changing the electromagnetic properties of air to provide confusing radar echos.<ref name="proceedings" />
