This application applies to the field of target measurement technology at firing ranges, providing a method, system, storage medium, and processor for post-mission multi-target trajectory measurement at firing ranges. This method departs from the traditional "separate first, then rendezvous" approach, instead employing a "rendezvous first, then separate" process. First, it utilizes the azimuth and elevation angles of the target relative to multiple stations to perform combined rendezvous calculations for targets at various times, obtaining the three-dimensional position coordinates of multiple targets at each time point. This achieves dimensionality enhancement of the data to be separated. By introducing additional one-dimensional data, the overlap between target data is significantly reduced, lowering the difficulty of trajectory separation. Simultaneously, an unsupervised learning method—a clustering algorithm—is introduced. This algorithm can group data without any guidance and is highly efficient. The post-mission multi-target trajectory measurement system at firing ranges using this method also achieves the aforementioned effects.
