The invention belongs to the field of air traffic control radars, and particularly relates to an S-mode secondary radar adaptive matching target calling method. According to the calling method, a calling list maintenance module processes target information sent by an extension in order to receive secondary radar data and calculates a sector to which the target belongs; a sector calling link list is indexed through a sector indexing list, azimuths and distances between the target and other targets in the sector are compared, and according to a rule in which the azimuths are increasing and the distances are from the near to the distant, the calling link list for the sector to which the target belongs is updated; a calling control module queries calling trigger sent by a time sequence sending module, when the calling trigger arrives, an antenna mechanical azimuth is acquired, an antenna beam coverage range is calculated, corresponding targets are extracted from the sector calling link list, ranking is carried out according to target attribute vector equation values, and a target sending time and a receiving time are calculated. Targets in participation in calling can be accurately estimated and ranked, and the time utilization rate and the calling efficiency can be enhanced.
