Claim:
1. A signal classifying unit comprising a processor; a signal receiver for receiving and recording a radio-frequency signal; wherein said receiver is interruptible such that segments of the recorded radio-frequency signal are non-contiguous segments; a medium storing instructions executable by the processor for simulating contiguous segments by modeling said non-contiguous segments; wherein said instructions include instructions to: apply a coarse carrier frequency offset correction to said non-contiguous segments; apply a phase correction to said non-contiguous segments after said coarse carrier frequency offset correction is applied; apply a residual course frequency offset correction to said non-contiguous segments after said phase correction is applied to generate modeled contiguous segments; and, output a simulated continuous signal consisting of recorded continuous signal segments and modeled contiguous segments; a signal classifier receiving the outputted simulated continuous signal for classifying the simulated continuous signal.
