"Anyone can fix a sensor array but no one can fix the holosuites like that idiot brother of mine."
– Quark, 2373 ("Rapture")

Display of duotronic sensor array in use

A sensor array was a device in which a group of sensors were combined; an example was the forward sensor array on Galaxy-class starships. Subprocessors were part of a sensor array. (TNG: "The Game")

In April 2151, when observing Enterprise NX-01, Captain Jonathan Archer was eager to get a look at her lateral sensor array. (ENT: "Broken Bow")

A Vulcan sensory array beneath the monastery of P'Jem

A commando from the Andorian Imperial Guard searched for a long range sensor array hidden beneath the Vulcan monastery at P'Jem on three occasions in 2151. On their first two visits there, no such sensor array was found, so they left within a day. During their third visit, in June of 2151, though, a covert sensor array was indeed discovered by an Andorian team of four, led by Commander Thy'lek Shran, and a landing party from the NX-class starship Enterprise NX-01, led by Captain Archer. The entry to the room housing the sensor array was hidden by a tapestry in the reliquary of the monastery. (ENT: "The Andorian Incident")

In the script for "The Andorian Incident", this Vulcan sensor array was described thus; "We can see a tall, vast, cylindrical chamber, multi-leveled, filled with sophisticated surveillance equipment – at least three stories tall. Hundreds of databanks are glowing and beeping. It's a massive intelligence gathering facility […] [with] consoles far below. It's an astonishing sight."

The USS Enterprise used a duotronic sensor array. This ship, and its fellow Constitution-class ships, were equipped with two sensor arrays. They were located on the top and bottom of the primary hull. (TNG: "Datalore"; DS9: "Trials and Tribble-ations")

The location of the aft lateral sensor array in the secondary hull of the Enterprise-B

In 2293, the location of the aft lateral sensor array was labeled in the USS Enterprise-B master systems display on the ship's bridge. (Star Trek Generations)

In 2367, the Galaxy-class starships had at least two systems managing the sensor arrays. They were the lateral sensor array system and the primary sensor array system. In that year, when Data hijacked the USS Enterprise-D, he issued a command override on these systems giving him complete control of the systems from the bridge. (TNG: "Brothers")

Commander William T. Riker suggested running a diagnostic on the USS Enterprise-D's forward sensor array when the two-dimensional beings were first detected. (TNG: "The Loss")

Even an enhanced sensor array aboard the Enterprise-D wasn't able to locate the transformed Geordi La Forge on the surface of planet Tarchannen III. (TNG: "Identity Crisis")

When studying the Phoenix Cluster in early 2368, only one long-range array was available for fifteen science teams. The available bandwidth was increased, however, by multiplexing the array. (TNG: "The Game")

In 2369, Chief Miles O'Brien and his assistant Neela did modifications to several systems of Deep Space 9. O'Brien told Neela to re-route the signal enhancement module to the main sensor array. (DS9: "Duet")

When the Starfleet crew of Deep Space 9 was forced to hand over the station to the Alliance for Global Unity-controlled Bajoran Militia, they sabotaged the sensor array. (DS9: "The Siege")

In 2370 the Albino had a subspace sensor array inside his base on Secarus IV. The Legendary Klingon Captains Kang, Koloth, and Kor along with Dax destroyed it to prevent the Albino from finding them when they went on their vendetta. (DS9: "Blood Oath")

In 2371, in the mirror universe, Jennifer Sisko was working on a transpectral sensor array that would allow the Alliance to easily locate Terran ships in the Badlands. (DS9: "Through the Looking Glass")

In 2372, Kar damaged the lateral sensor array on Commander Chakotay's shuttlecraft after attacking it. (VOY: "Initiations")

Dukat holding Ravinok's sensor array fragment

The same year, Razka Karn acquired a part of the forward sensor array of the Ravinok made of an uridium alloy. (DS9: "Indiscretion")

Jadzia Dax mentioned that the primary sensor array of the USS Defiant could not locate life signs when the cloaking device was activated. (DS9: "The Way of the Warrior")

In early 2373, Chief Miles O'Brien was able to reroute data from a Jem'Hadar attack ship's sensor array to a tricorder. (DS9: "The Ship")

The Dominion constructed a massive sensor array in the Argolis Cluster in the early months of the Dominion War. It was powerful enough to detect starships at least five sectors away. In 2374, Jadzia Dax commanded the Defiant in a successful mission to destroy it. (DS9: "Behind the Lines")

In 2375, Chakotay managed to find a way out of chaotic space by routing the USS Voyager's sensor array through the ship's deflector dish, which maximized the deflector's amplitude. (VOY: "The Fight")

In late 2375, a Romulan colony in the Unroth system began repairs on their long-range sensor array. This weakness was discovered by Thot Gor, who planned an attack. (DS9: "Strange Bedfellows")
