基于通用航迹起始模型的一步延迟新算法

A New Algorithm of One-step Delay Based on Universal Tracking Initialization Model

针对杂波环境下的快速目标航迹起始问题,提出一种新的航迹起始算法,该算法结合了一种新的航迹起始模型和一步延迟航迹起始算法的优点。其主要思想是在普通航迹起始模型的基础上,增加了一级中间航迹,并采用一步延迟航迹起始算法,利用相邻两个采样周期的量测,计算累积新息,剔除虚假航迹、分裂航迹。仿真结果表明:该算法比一般的逻辑算法设计灵活性更强,虚假航迹起始概率也明显下降。

A new algorithm is proposed to solve the problem of quick target tracking initialization in clutter. The advantages of a new track initial model and one-step delay approach are integrated. An intermediate stage is added to the current common track initiation model. The one-step delay approach is used in processing the intermediate track. Two scan measurements is used for calculating the cumulative innovation and eliminating the false tracks. By this algorithm, the design flexibility is improved and that probability of false tracks is reduced.
