摘要

摘要: 交互式思想在多模型定位中獲得廣泛應(yīng)用，但在多系統(tǒng)跟蹤定位中應(yīng)用較少。該文借鑒交互式思想提出交互式多系統(tǒng)跟蹤定位算法。該算法利用已獲得的估計(jì)信息進(jìn)行系統(tǒng)間定位信息的直接交互，然后進(jìn)行多系統(tǒng)并行濾波，并利用各系統(tǒng)濾波新息和方差對(duì)系統(tǒng)概率進(jìn)行實(shí)時(shí)更新，將估計(jì)結(jié)果按照系統(tǒng)概率加權(quán)融合輸出。通過(guò)跟蹤機(jī)動(dòng)目標(biāo)的仿真實(shí)例，可以看出該算法能夠根據(jù)定位系統(tǒng)的性能及時(shí)調(diào)整系統(tǒng)概率，有效改善多系統(tǒng)下目標(biāo)跟蹤定位性能。

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.
