摘　　要：介绍了一套自主开发和实现的无线声阵列传感器网络多目标跟踪平台。在相关的多目标跟踪技术的基础上,结合无线声阵列传感器网络的特点,对系统平台的工作流程进行了整体设计并实现了相关算法模块,并在该平台下进行了多目标跟踪实验。实验中利用随机部署在实验区域中的多个声阵列传感器实现了对多个目标实时跟踪,同时还根据实验数据的分析建立了多目标下声阵列传感器的量测模型,并展示了平台下多目标跟踪实验的总体效果及各支撑模块的性能分析。实验表明该平台的设计达到预期要求,是无线声阵列传感器网络在多目标跟踪领域的前沿研究和实践。In this paper, an independently designed multi-target tracking platform based on acoustic array sensor networks is presented. The working flow of the platform is designed; the related algorithm modules are implemented based on the technology of multi-target tracking in WSN and the characteristics of acoustic array sensor networks. And then multi-target tracking experiment is conducted. In the experiment, using multiple acoustic sensor arrays randomly deployed in the sensing field, multi-target tracking is successfully realized. Meanwhile, based on the experimental data, a model of acoustic array sensor under multi-target scenario is established; the overall effect of the multi-target tracking experiment is described and the performance of each module is further analyzed. Experiment result shows that the platform fulfills the expected requirements. The introduced platform is an advanced study and practice on multi-target tracking based on wireless acoustic array sensor networks.
