CAT (1)Clear Air Turbulence
CAT (2)Computer Aided Transceiver, proprietary control interface

But since Yaesu, who seems to be the originator of "CAT", uses
it in their FRG-100 receiver, Computer Aided Tuning would indeed be
more descriptive.

And given that the original poster did not seem to be clueless and
posting an off-topic question here, clearly the "CAT" relates to
radio, and so many of the replies are irrelevant.
