Design Of Multi-tracking Radar Plot Fusion System

In recent years, multi-radar data fusion has been widely used in military field. With the help of multidimensional data of distributed radars, the system will get a better understanding of the external environment. As a result, it will get a better detection and tracking of moving targets. This paper mainly focuses on the design of multi-tracking radar plot fusion system.After introducing the multi-sensor data fusion and radar clutter filtering algorithm, this paper designs a plot fusion system for the multi-tracking radars. Through space aligning and time aligning, this paper completes the unity of space and time of multi-radar data using the platform navigation information. Radar points have bulk distribution. By clustering and fusion estimation, the multi-radar tracking turns into the single radar tracking. In track processing, this paper updates all tracks through several association rules, such as vertical distance and angle threshold. Finally, the mixed coordinated adaptive α-β filter is used to realize filtering and prediction. Simulation and test indicate that the plot fusion system has a good performance on objective tracking of multi-radar.
