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通过材料成像系统，通过不透明介质定位人体目标。该技术还将为地面探测应用提供广域地下传感。第一阶段的测试结果显示，该系统有能力探测建筑物墙壁对面的人体目标，以及穿透10米厚花岗岩墙壁的人体目标。第二阶段研究的重点在于软件开发，以分类目标的下行剖面，跟踪目标，并计算目标;和硬件开发，以消除对外部现成的接收机的需要。后一项工作还需要开发软件，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。 该技术有两个主要应用，即态势感知和地下调查。前者对于早期市场进入最具吸引力，包括国土安全、警察/消防/搜索和救援，以及军事行动，其中寻找墙壁、植被、雪、火或其他不透明介质对面的人类主体的位置。后者包括地球物理勘探、矿体调查、公用设施探测和定位、路基和桥梁地下扫描、裂缝和空隙的探测、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.
