Scanning systems which produce records of electromagnetic input signals are usually subject to random impulse interference which may seriously degrade the records. An impulse noise suppressor employing digital techniques has been developed which has general applicability to such systems and which has been employed with success in a meteor radar installation and a thermal infrared scanning system. The results of field tests are presented verifying the usefulness of the suppressor with the meteor radar system. When used in conjunction with a digital signal averager the improvement is equivalent to a tenfold increase in transmitter power, with the added advantage that the signal output is suitably conditioned for further computer processing.
