Claim 19:
20. A system comprising:
at least one computing device; and
a non-transitory computer-readable medium storing computer-executable instructions that when executed by the at least one computing device causes the at least one computing device to:
while communicating on a first channel, receive a set of electromagnetic signals;
estimate frequencies for the set of electromagnetic signals;
calculate a variance of the estimated frequencies;
based on the calculated variance, determine whether the set of electromagnetic signals are radar signals;
if it is determined that the set of electromagnetic signals are not radar signals, continue to communicate on the first channel; and
if it is determined that the set of electromagnetic signals are radar signals:
stop communication on the first channel;
select a second channel; and
communicate on the second channel.
