【摘要】 论文主要研究多目标跟踪问题。数据融合是一种新兴的信息处理技术，它是适用于一个系统中使用多传感器这一特定问题而展开的一种信息处理的研究新方向，并在近几十年中得到了很大的发展，已经应用于诸多军事和民用领域。 由于数据融合是许多传统学科和新兴工程领域相结合而产生的一个新的前沿技术领域，论文首先阐述数据融合这一门新兴的信息处理学科的意义、理论基础、实现技术和研究现状，提供了有关数据融合研究领域的一个概观。论文的重点是在数据融合中的多目标跟踪领域。 在多目标跟踪领域，国内外的学者已经提出了很多在杂波环境下对多目标跟踪的算法，论文在收集大量国内外资料的前提下，指出每种算法的优缺点，综合各种算法，总结出了一种适合工程应用的模型，其中包括了机动目标采用“当前”统计模型。论文针对多杂波环境下的高度机动目标，依据多传感器数据融合的理论基础，基于目标跟踪领域中的概率数据关联算法，对于三个机动目标在杂波环境下的轨迹进行跟踪，并在Matlab环境中，完成了多目标融合跟踪各个阶段的算法仿真，取得了满意的仿真结果，从而证明了整个系统的数据融合目标跟踪算法的有效性。 论文对多传感器条件下的多目标跟踪理论进行了阐述，并在了解了众多国家在此领域的发展近况后，预测了今后多目标跟踪的发展方向。更多还原

【Abstract】 In this thesis, the problem of target tracking has been studied. Data fusion is a burgeoning field of information processing technology, which was carried out in conditions concerning a system equipped with several sensors. In recent years, data fusion has been developed greatly and been used in many military and civilian fields.Data fusion is a new foreland technology field, which was generated by combining many traditional subjects and burgeoning subjects, so this thesis expatiate on the meaning, theory foundation, actual technology and research status of data fusion, which was a newly burgeoning subject deal with information. This thesis also applies a survey in the data fusion research field and the focus of this thesis is mult-target tracking field of the data fusion.In the field of multi-target tracking, scholars in China and other countries have presented many algorithms that treat with multi-target tracking in clutter. On the basis of collecting a lot of data in many countries, this thesis pointed out the virtues and shortcomings of every algorithm and concluded a model that suitable for the application in engineering. That model includes a ’currently’ statistical model for the maneuvering targets.To resolve the question of tracking highly maneuvering targets in clutter with different sensors, the theory of multi-sensor data fusion and algorithm of joint probabilistic data association have been analyzed in depth. In this thesis, with the using of MATLAB simulating tool, it accomplished the tracking of three maneuvering targets in clutter and completed the algorithm emulation ofevery phase in multi-target tracking. From the satisfied result of simulation, the validity of target tracking algorithm in whole data fusion system has been proved.The multi-target tracking theory on the condition of multi-sensor was discussed in this thesis and the future develop direction of multi-target tracking was forecasted on the basis of knowing much recent situation of many countries in this field.更多还原
