SBIR Phase I: Combining Time Compressed Synthetic Pulses and Frequency Scalable Antennae to Optimize UWB Sensor Dynamic Range

这个小型企业创新研究(SBIR)第一阶段项目建议利用不断发展的传感器优化概念，促进通过洞穴、山坡、建筑物、树叶、雾和其他不透明材料探测人类目标。这项技术将在国土安全、机场安全、敌对警察行动、高中和其他人质事件以及搜救方面有广泛的应用。第一阶段的工作将包括对模拟和真实数据的可行性研究，以确定新颖的脉冲和天线几何结构是否将同时提高演变中的超宽带传感的动态范围和分辨率。这一提议的假设表明，这些改进将促进通过更广泛的材料对人类和其他目标进行无人值守的遥感，而不会牺牲扩展的范围、分辨率和杂波抑制。这项工作将包括现场测量，以评估选择脉冲形状、天线几何形状和加载方案的初始潜力，以通过各种低损耗和高损耗不透明材料来探测人类。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，其中寻求人类主体的位置和在墙、植被、雪、火、雾、黑暗、烟雾或其他不透明媒体的对面探测可能的武器。后者包括地球物理勘探、矿体调查、公用事业探测和定位、路基和桥梁地下裂缝和空洞扫描，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 Small Business Innovation Research (SBIR) Phase I project proposes to capitalize on evolving concepts for sensor optimization that will facilitate the detection of human targets through caves, hillsides, buildings, foliage, fog, and other opaque materials. This technology will have broad application in homeland security, airport security, hostile police action, high school and other hostage events, and for search and rescue. The phase I effort will include a feasibility study of simulated and real data to determine if novel pulse and antennae geometries will simultaneously enhance the dynamic range and resolution of evolving ultra-wideband sensing. The hypothesis of this proposal suggests that these improvements will facilitate unattended remote sensing of human and other targets through a wider range of materials without sacrificing extended range, resolution, and clutter suppression. This effort will include field measurements to assess the initial potential of select pulse shapes, antenna geometries, and loading schemes to detect humans through a variety of low-loss and high-loss opaque materials.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 and the detection of possible weapons on the opposite side of walls, vegetation, snow, fire, fog, darkness, smoke, or other opaque media is sought. The latter includes geophysical exploration, ore body investigation, utility detection and location, road-bed and bridge subsurface scans for 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.
