Shield can jam radars, period. For once, they just don't treknobabble us to death, they just say what the shields do, not how the fuck they do it ( not surprising, it was in TOS - "Assignment : Earth" IIRC ) .Darth Fanboy wrote:How does it "jam" a radar? Stealth aricraft today use special paints and designs to make themselves invisible they don simply "jam" the wave. Its not like a radar wave can pass through a cloaked ship just because you couldn't see it.
BTW cloaked ships in modern trek do something like bending EM rads around them, and probably retaining their own IR heat into their cloak bubble.
Actually older Klingon warcruisers gave off some sparse gamma or X-ray rads ( the ep in which an old cruiser, the T'Ong, reawakes her crew after a 80-years cryosleep, mentions it ) , but by the time of TNG it had been fixed. IR seem too obvious even for the Feddies.If not radar then what about Infra red? If the other ship is giving off heat then wouldn't one of those scans pick it up Or maybe even Geordi's damn visor.
