A method for receiving at least one signal emitted by at least one emitter includes defining a first dwell associated with a first signal. The first dwell has a frequency range that overlaps at least a portion of a frequency range of a second signal. The method also includes detecting the second signal responsive to the first dwell if the first dwell satisfies at least one criterion for detecting the second signal. The method further includes rejecting the second signal responsive to a characteristic of the second signal if the first dwell fails to satisfy the at least one criterion.
