合理的跟踪门将大大提高数据关联算法的性能,其重要性不言而喻。在椭圆跟踪门的基础上加入了速度和角度限定,进一步减少了波门中杂波的个数和计算量,提高了关联跟踪的质量。对飞机的俯冲运动进行了仿真,证明了算法的有效性和可行性,同时通过对比分析,得出此算法在密集杂波环境下有着更好的效果。 Reasonable track keeper will greatly improve the performance of data association algorithm, its importance is self-evident. Based on the ellipse tracking door, the speed and angle limit are added, which further reduces the number and amount of clutter in the gate and improves the quality of correlation tracking. The subduction of the aircraft is simulated, which proves the effectiveness and feasibility of the algorithm. At the same time, through comparative analysis, it is concluded that this algorithm has better effect in dense clutter environment.
