多雷达多目标航迹起始算法研究

提出了一种基于聚类分析与逻辑法相结合的集中式多雷达航迹起始算法。首先采用聚类算法对传送到融合中心的数据进行聚类,使每一类中的数据代表同一个目标,并找出聚类中心作为等价的单雷达的量测,从而使航迹起始过程相对简化;在起始算法中根据目标的运动特点,对逻辑法进行了一定的改进。仿真试验证明了该算法的有效性。

A Practical Algorithm of Multi-radar Multi-target Track Initiation

Track initiation is a precondition to carry out tracking targets effectively.In the paper,an algorithm of track initiation based on clustering and Logic-Basic approach is proposed.First.,the data transmitted to the fusion center are clustered,which makes the data in each cluster stand for the same target.Then the center of each cluster is found and taken as the measurement from single radar.By doing so,the track initiation process is simplified.According to the characteristic of targets' movement,an improvement is made in the Logic-Basic approach.Simulation results indicate that the algorithm is effective.
