Abstract:
1. A method of processing tracks of air targets moving in a space of interest, the method comprising: detecting at a plurality of sensors, the detecting originating from the plurality of sensors being synthesized as detections of a single dummy radar; establishing a two-dimensional grid of a stereographic projection plane of the space of interest, the two-dimensional grid being divided into a plurality of cells of rectangular shape, wherein a cycle period of the single dummy radar is subdivided in a plurality of internal virtual time segments of determined duration; storing, in a buffer memory of a radio tracking system, all detections produced during at least one internal virtual time segment; and correlating, via a correlation function, the detections with the tracks of the air targets on a basis of a first proximity criterion between the cells of the two-dimensional grid containing the detections and the cells of the two-dimensional grid containing the tracks of the air targets, said correlation function being triggered by a message indicating an end of at least one internal virtual time segment, the correlation being made on a basis of the detections stored in the buffer memory during the at least one internal virtual time segment.
