Patent ID: 8824544

Claim:
A system of recovering missing spectral information in a wide band signal comprising: at least one receiver for receiving data signal responses from a target area; the received data signal responses being spectrally notched with respect to at least one predetermined spectrum; at least one processor for recovery of data from the data signal responses operatively connected to the at least one receiver that digitizes the received data signals; the at least one processor operating to generate a wideband signal that corresponds to a signal that is not spectrally notched; a first dictionary comprising time-shifted unnotched versions of a transmit signal based upon spectra containing the at least one predetermined spectrum, a second dictionary comprising a plurality of spectrally notched time-shifted versions of the transmit signal corresponding to the transmit signal contained in the first dictionary; whereby the first and second dictionaries operate to provide data to the at least one processor to compensate for the spectrally notched responses in order to provide a signal that corresponds to a signal that is not spectrally notched.
