Sensor jammer

A sensor jammer was a type of jammer capable of blocking or fooling sensors. Powerful generators flooded areas with static and random signals, effectively overwhelming and confusing local sensors. Starships using sensor jammers could conceal their exact location using a sensor jammer, but the downside was that the vessel also broadcast its general location. Sensor jammers were indiscriminate and fouled the sensors of friends and foes alike.

This could effectively cause a ship to go unnoticed by any possible observers, and also to prevent an attacker from gaining a weapons lock on the ship.
