Multiple-sensor tracking processing method with reduced latency time

摘要

A multiple-sensor tracking method, notably implemented in an air traffic control system, making it possible to reduce the latency time introduced by the tracking system, characterized in that the correlation (302) and association (303) functions work on the basis of membership of the detections (502) and of the tracks (503, 504) to cells (510, 511) defining a subdivision into a grid (501) of the surveillance area represented on a stereographic projection plane.

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.
