Airborne phased array radar track association method

The invention discloses an airborne phased array radar track association method, which belongs to the technical field of radar track tracking, and comprises the following steps of S1, association step division; S2, judging a radial speed threshold; S3, performing threshold cross judgment ; and S4, continuing the track. According to the method, by improving reliability and real-time performance of track association, the track tracking quality of the airborne phased array radar is improved, especially under the conditions of platform motion, large number of tracking targets and strong environmental clutter; correlation threshold cross judgment is carried out under various coordinate systems, that is, threshold judgment is carried out by using target motion characteristics, coupling of radar measurement azimuth and measurement distance errors is avoided, and meanwhile, Doppler precision is not lost; when the target is not followed, the followed-losing track and the new initial track are continued, so the followe
