Abstract:
1. A method for classifying signals occurring in a frequency band, comprising: a. detecting power spectral information of the radio frequency energy; b. detecting signal pulses of radio frequency energy in the frequency band from said power spectral information; c. accumulating data pertaining to detection of said signal pulses in the frequency band over time, wherein said accumulating comprises accumulating data for one or more characteristics selected from the group consisting of: pulse center frequency, pulse bandwidth, pulse duration, time between pulses and number of different active pulses, and wherein the reference data associated with each of a plurality of known signals comprises one or more characteristics selected from the group consisting of: pulse center frequency, pulse bandwidth and pulse duration; d. comparing the accumulated data against reference data associated with known signals; and e. classifying one or more signals occurring the frequency band based on the step of comparing.
