'''Electronic countermeasures''' (abbreviated '''ECM''') consist of technologies and techniques used to defeat enemy [[sensor]] systems, both in combat and in other situations. They can take the form of sensor jamming, stealth systems, decoys, and [[cloaking device]]s (which are a futuristic type of active stealth).

==Spoofing==
Spoofing is an effort to fool enemy sensors into reporting false information.  If successful, the sensor will report detecting something different from what is actually present.  A spoofing system might send out signals or energy patterns consistent with something harmless or friendly, disguising an approaching threat.  Spoofing might be accomplished by configuring a vehicle to reflect active sensor waves in the same pattern as a friendly vehicle or by mimicking the transponder transmissions of a friendly vehicle.

==Decoys==

A decoy is a type of spoof that consists of an expendable vehicle designed to present the same image to sensors as a more important vehicle. For example, a submarine might launch a torpedo designed to sound like the submarine itself. The purpose of a decoy may be to distract guided missiles from their intended target or to divert enemy resources away from an actual threat.

The most noteworthy ECM in ''[[Babylon 5 (series)|Babylon 5]]'' is the stealth technology employed by the [[Minbari Federation]].  This technology makes Minbari ships essentially invisible to enemy [[sensor]]s if they choose to be.  Even when running their own active sensors, Minbari ECM technology prevents the sensors of the other Young Races from obtaining weapon locks.

In ''[[Mass Effect]]'', some ships have special engines and heat sinks that allow them to operate for a period of time without radiating any heat. This is effective in the setting, where infrared sensors are the primary means of detecting starships.
