A method of identifying a signal type uses parameters of the signal as a basis
for automatic identification. A signal of interest is selected from a display of
a spectral waveform for a specified frequency. An occupied bandwidth for the signal
of interest is estimated and, if the occupied bandwidth is common to more than
one known signal type, a complementary cumulative distribution function of peak
power for the signal of interest is estimated. The signal type may be identified
as a function of these parameters. Additionally the frequency of the signal of
interest may be compared with a database of spectral assignments for known signal
types to provide further information about the signal of interest.
