Claim 0:
1. A method for identifying and verifying multi-mode frequency hopping signals, the method comprising:
scanning, for a select time period, to capture a first set of signals, wherein the first set of signals comprises a signal of interest (SOI);
identifying from the first set of received signals a second set of signals having on times longer than a specified minimum dwell time;
providing a plurality of signal profiles associated with a plurality of pulsed patterns having expect dwell times and cycle times of the signal of interest;
identifying from the second set of signals a third set of signals that match at least one of the plurality of signal profiles;
determining whether the third set of signals meet a first criterion;
receiving demodulated data regarding the third set of signals;
upon determining the first criterion is met, obtaining characteristic information for each of the third set of signals;
verifying, using the characteristic information and demodulation data, for each of the third set of signals their cycle time, dwell time, and header information;
determining whether the verification of the third set of signals produced a match; and
upon determining of the match, providing an indication of the signal of interest.
