中文摘要: 无线被动定位跟踪是一项通过利用目标对无线信号传播的影响来实现对目标位置进行定位和移动轨迹跟踪的技术。目前绝大多数已有的被动定位跟踪技术都是利用目标对无线信号强度(RSS)的影响实现定位跟踪,然而在室内环境中,由于多径效应影响,RSS值波动剧烈,定位跟踪性能差。针对该问题,本课题提出基于无线信道状态信息利用普通商业无线设备实现室内复杂环境下普适的低成本的被动定位跟踪。本课题首先研究从普通商业WiFi无线网卡中获取无线信道状态信息,探究目标出现、移动对于无线信道状态信息的影响。其次研究基于位置信号指纹信息来实现室内单目标到多目标的高精度被动定位跟踪。同时研究利用无监督学习的方法实现室内单目标到多目标的被动定位跟踪。最后研究实现室内被动定位跟踪应用平台。本课题将建立完善的基于无线信道状态信息的室内被动定位跟踪技术,促进其在室内环境下应用的普及。

英文摘要: Wireless passive localization and tracking is an emerging technique that makes use of the interference effect on wireless signal transmission caused by a target to realize localization and trail tracking. Most of the existing methods utilized the Received Signal Strength (RSS), but RSS is volatile due to the multipath effect, especially in the indoor environment. The accuracy of localization and tracking is accordingly poor. To overcome these problems, this proposal propose a novel scheme to realize universal and low-cost indoor passive localization and tracking based on ordinary commercial wireless devices. Firstly, we will extract the channel state information from the commercial WiFi wireless card and research on the effect of target appear and movement on channel state information. Secondly, we will explore the high-accuracy passive localization and tracking based on location signal fingerprint for single objective and multi-objective. While, we will study the indoor passive localization and tracking based on unsupervised learning methods from single objective and multi-objective. Finally, an indoor passive localization and tracking application platform will be implemented. The above works build the method of realizing indoor passive localization and tracking based on wireless channel state information, and promote its application and popularization in the indoor.
