摘要

摘要: 交互式思想在多模型定位中获得广泛应用，但在多系统跟踪定位中应用较少。该文借鉴交互式思想提出交互式多系统跟踪定位算法。该算法利用已获得的估计信息进行系统间定位信息的直接交互，然后进行多系统并行滤波，并利用各系统滤波新息和方差对系统概率进行实时更新，将估计结果按照系统概率加权融合输出。通过跟踪机动目标的仿真实例，可以看出该算法能够根据定位系统的性能及时调整系统概率，有效改善多系统下目标跟踪定位性能。

Abstract: Interacting algorithm is widely used in multi-model target tracking, but it is rarely used in multi-system target tracking. In this paper, the interacting idea is used as a reference, and an interacting multi-system tracking algorithm is proposed. The direct interaction between systems is finished based on their former state estimation. Then system probabilities are updated using innovation and its covariance from the parallel filters. Finally, weighted fusing results are achieved on the updated probabilities. The simulation result of tracking a maneuvering target shows that system probability can be adjusted based on its performance immediately, and the tracking performance can be improved effectively.
