Patent ID: 6842137

Claim:
A method of detecting an emitter signal using a receiver having a tuning step size, the method comprising acts of: a) creating a first dwell to detect a set of emitters, the first dwell being defined, in part, by a first frequency range having a first minimum frequency and a first maximum frequency; b) determining if the first minimum frequency of the first dwell is an integer multiple of the tuning step size; c) if the first minimum frequency of the first dwell is not an integer multiple of the tuning step size, shifting the first frequency range of the first dwell to generate a second frequency range having a second minimum frequency and a second maximum frequency, such that the second minimum frequency of the first dwell is an integer multiple of the tuning step size; and d) determining if a portion of a third frequency range of an emitter of the set of emitters that is covered by the first frequency range is not covered by the second frequency range.
