It means a radar. Range relates to power and the rate at which it
decreases with distance. For example....if I stand in front of an
Aegis radar during a pierside test at sufficiently high power, I'm
toasted. But that same radar is radiating across streets and bridges
and houses a mile or two distant,

It might or might not be a radar.
If they are using some forms of localized waves as energy carrier (not very
likely today though) you can get toasted even if you were thousands miles away
from the emitter.
