摘　　要：航迹起始是多目标航迹处理中的重要问题。针对异步被动传感器系统航迹起始困难的问题,提出了一种基于蚁群导航思想的异步被动传感器航迹起始算法。该算法首先利用各传感器在多个扫描周期的测量建立候选目标集,采用极大似然法确定每一个候选目标的初始状态估计,然后再利用蚁群导航算法实现真实航迹的检测,最后由极大似然法估计出每一批目标的初始状态。仿真实验表明,该算法不但能够有效实现航迹起始,而且降低了虚假航迹的起始率。Track initialization is very important for multi-target track processing.An ant navigation based track initiation algorithm was proposed in this paper to overcome the existing problems in asynchronous passive sensor system.A set of candidate targets was built up at first using the measurements of the sensors at multiple scanning periods,and the initial track state estimation of each candidate target was determined by using the maximum likelihood method.Then the real track was detected by using ant navigation concept,and finally the initial target state was estimated using the maximum likelihood method.Simulation results show that the algorithm presented can initiate tracks effectively.Besides,the algorithm reduces the ratio of false track initiation.
