IFF MARK X/SIF 'DEFRUITER' AND ITS APPLICATION.

Abstract : An SIF signal 'defruiter' using inexpensive magnetostrictive delay lines as storage elements has been developed to the breadboard stage. It removes 90 per cent or more of the background clutter from IFF displays under high traffic density conditions. At little increase in cost, an all-mode bracket decode output and an emergency signal recognition and alarm signal circuit can be added. (Author)
