Comm/scan

"Comm/scan has detected an energy field protecting an area around the sixth planet of the Hoth system. The field is strong enough to deflect any bombardment."

- Maximilian Veers to Darth Vader

Comm/scan was a form of sensor technology used to detect energy readings and approaching starships. The Galactic Empire and later the Resistance made use of comm/scan technology.

History
"Comm/scan reports three Resurgent-class Star Destroyers and a larger capital ship. Unknown class, Dreadnought-sized. Preliminary estimated length seven thousand five hundred meters."

- PZ-4CO to Kaydel Ko Connix

The Galactic Empire utilized comm/scan technology to detect the deflector shield protecting Echo Base on Hoth prior to the Battle of Hoth.

The Resistance had comm/scan technology on D'Qar, using it to determine the quantity and size of starships comprising the First Order's attack force during the Evacuation of D'Qar. The First Order later used comm/scan to home in on the signatures of emissions given off by fleeing U-55 orbital loadlifters attempting to reach Crait, and gunners were able to shoot down several of the escaping craft.
