Abstract

PURPOSE:To make it possible to detect at a time the number of pulse strings included in arrival pulses and their pulse repetitive intervals, by classifying pulse intervals and then by performing specific processing. CONSTITUTION:Measurement data t1-tN of arrival times of external pulses are inputted from input terminal 1. Those signals are supplied to pulse repetition interval PRI filters 21-2k and pulse tm, only when a pulse exists in an interval expressed by tm-tk<t<=tm-tauk-1 prior to it, is allowed to pass. Pulse tm-tn existing in this interval is also outputted simultaneously. Signals passed through filters 21-2k are supplied to dividing circuits 31-3k for division tm/(tm-tn), complex trigonometric function arithmetic circuits 41-4k perform arithmetic exp[2piitm/ (tm-tn)], and accumulating circuits 51-5k perform addition expressed by formula -1. The number of pulse strings and their PRIs are detected by making comparisons with ¦DK¦ of outputs of circuits 51-5k.
