Abstract

PURPOSE:To decode an interrogation pulse at improved efficiency by installing a random pulse generator separately. CONSTITUTION:Video signals from a receiver are outputted through a decoder 1 and a random pulse generator 3 and, at the same time, the output is supplied to a decoder 1 throug a blanking gate generator 2. A blanking gate that has a specified decode suppressing time at the leading edge of a decoder output pulse is generated and decode is inhibited. Since the minimum interval of the random pulses generated in the random pulse generator 3 can be set at a specified blanking gate time, the result of systhesis with the random pulse from the random pulse generator becomes equal, the probability to suppress the interrogation pulse from an interrogater is improved.
