Interferometric dispersion

Interferometric disperson was a method whereby a vessel's deflector shield could be modulated to scatter RADAR.

Such a method was utilized the crew of the USS Voyager to remain undetected by Earth surveillance satellites, after having accidentally traveled back in time from the year 2373 to 1996. The method was later used by Lieutenant B'Elanna Torres, while she and Commander Chakotay were piloting a shuttlecraft on a mission to stop Henry Starling, a 20th century industrialist who had stolen a timeship from the 29th century.
