SBIR Phase II: A High Frequency Beam Steered Electromagnetic Impulse Radar to Locate Human Targets Through Opaque Media

该SBIR第二阶段项目将开发一种穿透材料成像系统，该系统将通过不透明介质定位人类目标。该技术还将为地面探测应用提供广域地下传感。一期实验结果表明，该系统具有对建筑墙面和10米以上花岗岩墙面的人体目标进行探测的能力。第二阶段研究的重点在于软件开发，以便对下射程剖面中的目标进行分类、跟踪和计数目标；以及硬件开发，以消除对外部现成接收器的需求。后一项工作还需要软件开发来为分类算法处理数据。该项目的独特创新之处在于，它可以进行全区域调查，并从固定位置定位固定目标。这项技术有两个主要应用：态势感知和地下调查。前者对早期进入市场最具吸引力，包括国土安全、警察/消防/搜救和军事行动，即寻找人类主体在墙、植被、雪、火或其他不透明媒体对面的位置。后者包括地球物理勘探、矿体调查、公用事业探测和定位、路基和桥梁地下扫描，以寻找裂缝和空洞，以及从固定点进行无人值守的地面传感，以评估可用于预测地球或结构故障的地下变化。

This SBIR Phase II project will develop a through material imaging system that will locatehuman targets through opaque media. The technology will also provide wide area subsurface sensing for ground probing applications. The phase I results demonstrated that the system has the capability of detecting human targets on the opposite of building walls and through walls of granite over 10m thick. The thrust of the phase II research lies in software development to classify targets in the downrange profile, track targets, and count targets; and hardware development to eliminate the need for an external off the shelf receiver. The latter effort will also require software development to process data for the classification algorithms. The unique innovation of this project is that it can conduct full area investigations and locate stationary targets from a fixed location. There are two primary applications for this technology, situational awareness and subsurface investigation. The former, which is the most attractive for early market entry, comprises homeland security, police/fire/search and rescue, and military actions where the location of human subjects on the opposite side of walls, vegetation, snow, fire, or other opaque media is sought. The latter includes geophysical exploration, ore body investigation, utility detection and location, road-bed and bridge subsurface scansfor cracks and voids, and unattended ground sensing from a fixed point to assess subsurface changes that can be used to predict earth or structural failure.
