Targeting scanner
From Memory Alpha, the free Star Trek reference.
A targeting scanner (or Target Acquisition) is a part of the transporter system. It is used to locate objects which need to be transported.
In 2151 Commander Tucker informed Lieutenant Reed that the targeting scanners are online in about an hour, moments after the attack of an unidentified alien vessel. (ENT: "Silent Enemy")
Targeting scanners can also be used to aim weapons at a target, during a tactical scenario. In an alternate version of 1944, Armory officer Malcolm Reed attempted to use the targeting scanners aboard the NX class starship Enterprise to destroy a facility belonging to Vosk, the leader of the Na'kuhl. However, he was unable to lock on to the building with targeting scanners, so he used visual scanners instead. (ENT: "Storm Front, Part II")
