Radar scramblers

See also: radar jammers

This can function in at least 3 different ways without becoming a radar jammer:
* Causing radar blips to appear as fewer by somehow merging several blips. Possibly making one assume a small troop of armored soldiers is actually a large tank.
* Producing number of false blips, or dispersing large blips into many smaller ones. Making smaller force seem larger or large units collections of few smaller.
* Denying any guesswork on numbers and making one able to only say "there's something there" (e.g. a distorted region in radar, such as noise filling a region that does not occur normally).
