SBIR Phase I: Through-Building Device-free Localization for Emergency and Tactical Operations

这个小型企业创新研究（SBIR）第一阶段项目将研究无线网络的快速部署，目的是在战术通过建筑监视应用中实现无设备定位（DFL）。DFL仅使用部署在建筑物外部的简单无线电设备来定位建筑物内的人员。在警察或军事行动中，这些设备在建筑物周围投掷或发射，然后测量许多对设备之间的接收信号强度（RSS）。在部署后的几秒钟内，DFL系统就会显示出一幅追踪建筑物内人员和物体的地图。这样的系统需要快速部署技术和实时的无运营商网络配置。该项目将推动自配置和自适应无线网络的发展。将开发使用可重构天线来指导天线方向图通过建筑物的方法，而不管传感器如何着陆。对于无运营商部署，网络将具有自定位的设备，并学习要测量的特定无线电信道的统计信息。综合结果将表明，战术部署的无线设备可用于在进入危险建筑物之前快速获取有关居住者的情报。由于执法人员不知道墙的另一边发生了什么，每年都有许多人丧生，因此这个项目的广泛影响/商业潜力是巨大的。如果成功，该项目将为警察/SWAT和军事特种作战部队（SOF）提供产品，通过在进入危险建筑物之前提供可操作的情报来挽救生命。现有的穿墙成像雷达技术过于昂贵（10万美元），除了成本不敏感的应用。我们计划一个产品，因为它的低成本、小尺寸和易于使用，将成为警察部门和特种部队的标准装备。因此，我们将在780亿美元的监控设备市场中占有一席之地，该市场正以每年10-13%的速度增长。无线网络快速部署技术的发展将有利于广泛的环境监测和“物联网”系统。

This Small Business Innovation Research (SBIR) Phase I project will investigate the rapid deployment of wireless networks for the purpose of device-free localization (DFL) in tactical through-building surveillance applications. DFL locates people inside of a building using only simple radio devices deployed on the outside of the building. In a police or military operation, these devices are thrown or launched around the building, and then measure the received signal strength (RSS) between many pairs of devices. Within seconds of deployment, the DFL system shows a map tracking people and objects within the building. Such a system requires rapid deployment techniques and real-time operator-free network configuration. This project will advance the state-of-the-art in self-configuring and adaptive wireless networks. Methods for using reconfigurable antennas to direct the antenna pattern through the building regardless of how a sensor lands will be developed. For operator-free deployment, the network will have devices which self-localize, and learn the statistics of the particular radio channels to be measured. The combined results will show that tactically deployed wireless devices can be used to rapidly obtain intelligence regarding occupants before entering a dangerous building.The broader impact/commercial potential of this project are significant, as lives are lost every year because law enforcement officers do not know what is happening on the other side of a wall. If successful, this project will enable a product for police/SWAT and military special operations forces (SOF) which will save lives by providing actionable intelligence prior to entering a dangerous building. Existing radar technology for through-wall imaging is too expensive ($100k) for all but the most cost-insensitive applications. We plan a product that, because of its low cost, small size, and ease of use, will be standard equipment in police departments and in SOF teams. We will thus capture a portion of an $78 billion surveillance equipment market, which is growing at a 10-13% annual rate. Development of rapid deployment technologies for wireless networks will benefit a wide range of environmental monitoring and "internet-of-things" systems.
