History Main / PsychicRadar

* ''Series/BabylonFive'': telepaths, especially powerful ones, can detect people by their surface thoughts. The Psi Corps typically trains their telepaths to block out those thoughts to protect people's privacy (and the telepath's sanity). When Lyta Alexander's powers are upgraded UpToEleven by the Vorlons, she is shown to be able to detect which security camera is currently being used to watch her. Serves as a sort of PokeInTheThirdEye, when Sheridan and Garibaldi are watching her from the security office in an interrogation room. She's staring right at the camera. As soon as they switch to another camera in the same room, she turns to look at it, freaking them out.

* Professor Charles Xavier from the ''Film/XMenFilmSeries'' can detect people around himself, amplified greatly with Cerebro to find almost anyone in the world. In ''Film/X2XMenUnited'', he can even track a mutant who frequently teleports to a different place. Concentrating hard enough will give everyone on the planet a really serious PsychicNosebleed... followed by death.

* Charles Xavier from the ''Film/XMenFilmSeries'' can detect people around himself, amplified greatly with Cerebro to find almost anyone in the world. In ''Film/X2XMenUnited'' he uses it to allow him to track even a mutant who can teleport and it's further revealed that he can use it to sense the location of every mutant or every human on the planet. Concentrating hard enough will give them all a really serious PsychicNosebleed... followed by death.
* ''Film/StarTrekNemesis'' has Deanna Troi (even though she's not a full telepath) use her psychic connection to the Viceroy to not only pinpoint the location of the cloaked ''Scimitar'' but also specifically target its [[TheBridge bridge]]. The Viceroy realizes what's happening too late to stop it. This is only possible because Shinzon (with the help of the Viceroy) previously {{Mind Rape}}d her while she was having sex with Riker.

* ''VideoGame/CommandAndConquerRedAlert'' has the Psychic Sensor which allows the detection of enemy units outside of Line of Sight and the prediction of their movements. Also the Psychic Radar which psychically revealed sections of the battlefield.

* Some meisters in ''Manga/SoulEater'' can do this, notably Maka and Joe.

* One-Ness users in ''Manga/DestroyAndRevolution'' can sense each other and even when the power is being used.
* ''Manga/YuYuHakusho'' has this as a common ability.

* ''VideoGame/ScarletNexus'': Tsugumi's Clairvoyance power is frequently used in the story for her to be a SensorCharacter. In her backstory, Tsugumi overheard many things better off not knowing and telling others about them made people hate her, resulting in her becoming a ShrinkingVIolet and loving plants. Of note, in one conversation she brings up that she regularly sees inside of people’s organs, pointing out when Yuito has a stomach sickness. Her power is shared with the protagonists via PsychicLink to detect invisible enemies and which enemy is the real one in a DoppelgangerAttack. Her link with Luka also serves as RequiredSecondaryPowers to get the most out of his PsychicTeleportation, as he can’t go somewhere he can’t see safely.

* ''Manga/DragonBall'': The main cast has the ability, after a certain point, to sense each other's PowerLevel and relative location. They can also ascertain the identity of a new power source if it is known to them, and detect similarities in power signatures because one person is related to the other, was their tutor, or is connected in some other way. The power is originally taught by the Namekian, Kami, to Goku and disseminates through the cast from there, and seems to be nearly unheard of throughout the rest of the universe. This provides a major advantage to the protagonists in the Namek Saga, as Frieza's forces don't realize sensing their power is even a possibility, allowing the cast to evade them with relative ease.

* ''WesternAnimation/Incredibles2'': Jack-Jack shows the ability to know that his parents are nearby. While on the Everjust, he was able to locate Helen on the top deck. During the DVD extra ''WesternAnimation/AuntieEdna'', when the doorbell rings, Jack-Jack immediately knows that it's "Da-Daddy".

* Charles Xavier from the ''Film/XMenFilmSeries'', can detect people around himself, amplified greatly with Cerebro to find almost anyone in the world. In ''Film/X2XMenUnited'' he uses it to allow him to track even a mutant who can teleport and it's further revealed that he can use it to sense the location of every mutant or every human on the planet.

** This is only possible because Shinzon (with the help of the Viceroy) previously {{Mind Rape}}d her while she was having sex with Riker.

** Early editions had the Detect Life cleric spell, which could detect living creatures at a distance, and even through solid non-metal barriers.
** 2nd Edition introduced the psionic ability Life Detection, which allowed the user to detect the presence of living, thinking creatures within a limited area.

Appears in as many media as do the telepaths providing it, though like them, it's generally restricted to SpeculativeFiction and {{Superhero}} genres. It's especially common in VideoGames and TabletopGames. In film, TV, comics and animated media, use of this power will involve the PstandardPsychicPstance and high effort or contest with someone or something blocking your telepathic radar sweep can result in a PsychicNosebleed. It's also common to see this represented in Film and Television with the searching psychic's eyes overlaid over the sought-after characters hiding place.

* ''Franchise/StarWars'': As per the above quote, Jedi and Sith can sense the presence of other Force users; picking up a single other practitioner even amidst the myriad of minds on the Death Star. They can cloud their presences enough that Vader doesn't know just where Obi-Wan is, but he knows he is there.

* In the ''Literature/{{Necroscope}}'' novels people who have this "Talent" are called spotters, and are rarer even than regular Talents.

* A common ability in the ''Literature/{{Kadingir}}'' series, where people posses all sorts of PsychicPowers. This one comes in two flavours: the ''empathic radar'', which allows them to detect close-range lifeforms in general (animals and people, though specifying on what species or which individuals is increasingly difficult); and the ''mental radar'', which allows them to detect when close-range minds are activelly thinking about them, [[EnemyDetectingRadar with hostile intentions]] or otherwise.

* ''Series/DoctorWho'': Time Lords are capable of sensing each other as said in "Utopia/Last of the Time lords". [[FridgeBrilliance Since Time Lords periodically change their appearance, then it would make sense for them to evolve a way to recognize each other]]. However, it only seems to work when the Time Lord is actively paying attention.

** The Detect power could be defined as detecting life in general, or specific kinds of life in particular (minds, aliens, humans or whatever).

* ''Manga/MyHeroAcademia'': Ragdoll's Quirk is this trope and has such long-range and analytical capabilities that the [[BigBad Big Bad]] of the story, [[spoiler:aka All for One, cannot resist stealing it.]]

* Psychics such as Jean, Xavier, and [[spoiler: Harry]] are able to do this in ''FanFic/ChildOfTheStorm.''

* ''ComicBook/WonderWoman1942'': Diana's telepathy allows her to "see" the Saturnians even when they're using invisibility tech.

* ''Manga/DragonBall'': The main cast has the ability, after a certain point, to sense each other's powers.

Sub-trope of PsychicPowers, closely related to {{Telepathy}}. Commonly used by a SensorCharacter. May also invoke a touch of SensorSuspense. Compare SupernaturalSensitivity, for when a PsychicPower is used to detect the use of other powers and contrast SpiderSense, for a much less focused and instinctual version that detects imminent danger. See KillingIntent for a version that anyone can do.
