适用于机动载机平台的目标跟踪算法

Improved Target Tracking Algorithm for Maneuvering Carrier Airplanes

当载机机动时,惯导系统提供的载机数据信息存在滞后性,使用传统的跟踪算法将带来很大的跟踪误差。文章针对这个问题,结合实际工程应用,以理论推导的方式分析了载机机动时量测误差增大的原因,并引进虚拟量测误差,从改进目标观测模型的角度出发,提出一种跟踪算法的修正方案。本文分析并给出了仿真结果误差曲线,结果验证,当载机机动时,采用此方法仍可对目标进行比较有效的跟踪,是一种简单、有效的方法。

The data output by INS lags behind the current state of the carrier airplane when it is maneuvering. The lagged data will introduce high tracking error for traditional tracking algorithms. Aiming at the problem, this paper firstly theoretically analyses the reason that measurement error increases for the case that the carrier airplane is maneuvering, and then proposes a modified tracking scheme to improve the tracking precision when the carrier airplane is maneuvering. Experimental results show that the proposed method has a positive impact on the tracking precision for the case.
