Abstract

The invention provides a multi-radar track association and fusion method. With a central point of a spatial area range to be monitored as a center, a control spatial plane is divided into a plurality of horizontal strip spatial areas from one direction to the other opposite direction, serving as basic units to be scanned by a scanning system; during track association, tracks only in one certain strip spatial area and the adjacent one are searched for. The tracks in the current strip spatial area can be associated with only those in the certain strip spatial area and the adjacent one, namely track association can be achieved just by searching for the tracks in the limited range of several strip spatial areas, and by the use of the method, search calculation for track association is greatly reduced.

Description

technical field [0001] The invention relates to a multi-radar track correlation fusion method, in particular to a multi-radar track correlation fusion method suitable for use in an air traffic control (ATC) automation system. Background technique [0002] The reasonable information fusion of track data of multiple radars can not only directly expand the surveillance range to the entire airspace covered by each radar, but also comprehensively improve the quality of target surveillance and the reliability and impact resistance of the system itself. It has become the core technology necessary for the current air traffic control automation system. [0003] There are two main types of radar data fusion systems: centralized processing systems and distributed processing systems. [0004] The centralized structure concentrates the track information of each single radar to the multi-radar processing center for time-space alignment, track correlation, data interconnection, track filt...
