Abstract
An approach and apparatus for adaptive scanning for detection and classification of an RF signal. Time-domain and frequency-domain information are acquired and processed over a broad band of frequencies segmented into channels to produce signal features. The signal features are classified using a signal classifier into signal discriminants, from which a signal of interest is located and identified. Subsequent channel scans then place an increased relative or absolute dwell time on the channel believed to contain the signal of interest.
