The invention discloses a track and primary trace point pre-association method based on a sector block structure. The method comprises the following steps: after a data message from a signal processing subsystem is received, analyzing and extracting system states such as an azimuth angle and a primary trace point, and placing the primary trace point in a distance block of a corresponding azimuth sector according to the azimuth angle and the distance of the primary trace point; when the track is pre-associated with the primary trace points, firstly calculating a range block range where the primary trace points possibly associated with the track are located, then traversing all the primary trace points in the range block, and performing gate matching on the track and each primary trace point; adding the primary plot meeting the pre-association condition into an associable primary plot queue of the track; and when a track updating process is entered after the pre-association is finished, selecting the most suita
