Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. A system for identifying and verifying multi-mode frequency hopping signals, the system comprising
one or more computing device processors; and
one or more computing device memories, coupled to the one or more computing device processors, the one or more computing device memories storing instructions executed by the one or more computing device processors, wherein the instructions are configured to:
scan, for a select time period, to capture a first set of signals, wherein the first set of signals comprises a signal of interest (SOI);
identify from the first set of signals a second set of signals having on times longer than a specified minimum dwell time;
provide a plurality of signal profiles associated with a plurality of pulsed patterns having expected dwell times and cycle times of the signal of interest;
identify from the second set of signals a third set of signals that match at least one of the plurality of signal profiles;
determine whether the third set of signals meet a first criterion;
upon determining the first criterion is met, receive demodulated data regarding the third set of signals;
obtain characteristic information for each of the third set of signals;
verify, using the characteristic information and demodulation data, for each of the third set of signals their cycle time, dwell time, and header information;
determine whether the verification of the third set of signals produced a match; and
upon determining of the match, provide an indication of the signal of interest.
