The invention provides a multiple target tracking method of an air traffic control radar, and relates to the intelligent information processing field. The multiple target tracking method of the air traffic control radar can achieve real-time performance of tracking of the air traffic control radar. The multiple target tracking method of the air traffic control radar includes: obtaining measurement under a rectangular coordinate system; adopting section sector PHD filtering treatment, using regenerative measurement of a current sector at a previous moment to build a regenerative Gaussian item, obtaining regenerative target strength, and translating the regenerative Gaussian item into a preparatory survival Gaussian item; performing PHD prediction and updating on a survival Gaussian item and the preparatory survival Gaussian item of the current sector; using the measurement of the current sector and measurement of a prior sector to update the survival Gaussian item and the preparatory survival Gaussian item of the current sector; extracting a peak value so as to obtain target status; using the survival target status and the preparatory survival target status of the current sector to perform flight path management, using the preparatory survival target status to manage a temporary flight path, using the survival target status to manage a stabilized flight path, transiting the temporary flight path to the stabilized flight path, and simultaneously deleting unreliable flight paths, managing flight path numbers, and finally obtaining a flight path.
