Re: Radar Detectors



If these dudes are using K/Ka band will there be a problem when all the new satellite comms constellations go up in 2000 (ICO, Globalstar, Teledesic, Skybridge etc.) - I cannot remember which use K/Ka band but I am pretty sure some do, and these things are powerful - as are the uplinks from the handheld phone sets - even if Instant On still works with all that noise around any detector unit is likely to get very confused!?

Actually, there's instant-on radar as well as lidar (a/k/a laser).
Instant-on radar, operating on the K or Ka bands in America, generally
keeps the emitting element warm but not up to operating temperature
where it actually begins to generate signal. When Officer Speed pulls
the trigger the element is heated the rest of the way, thus generating
the desired wavelength emissions.

Lidar, like you indicated, generally uses LEDs and thus has no warm-up
time.
