1. A method for acquiring a frequency hopped signal with no prior knowledge about the frequency hopped signal, the method comprising: receiving an radio frequency (RF) signal at a receiver; converting the RF signal into a stream of digital signal levels; identifying energy detections in the stream of digital signal levels as possible hops of the frequency hopped signal; blindly acquiring a feature set for defining the frequency hopped signal from the energy detections; generating at least one waveform classification based on the feature set; directly acquiring energy detections from the RF signal based on the waveform classification; and reporting the at least one waveform classification as the frequency hopped signal.
