PROBLEM TO BE SOLVED: To classify pulse data of each received pulse accurately at high speed even when the pulse arrival times of arrival pulse signals are close to each other. SOLUTION: The pulse signal classification device comprises a receiving section for receiving pulse signals from a plurality of radio sources, a pulse data generating section for generating pulse data of the received pulse signals, a pulse interval classification processing section for calculating the pulse arrival time interval between the received pulses based on the pulse data and classifies the pulse data every radio source, a proximity pulse waveform extraction section for extracting waveform data of proximity pulses of which pulse arrival times are close to each other from each pulse data group, and a correlation processing section for performing correlation processing between the waveform data and average waveform data of each pulse data group. The pulse data of the pulse data group having large correlation value with the waveform data of the proximity pulse is replaced with the pulse data of the proximity pulse.
