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检测人类目标。这项技术将广泛应用于国土安全、机场安全、敌对警察行动、高中和其他人质事件以及搜索和救援。第一阶段的工作将包括对模拟数据和真实的数据进行可行性研究，以确定新的脉冲和天线几何形状是否将同时增强动态范围和不断发展的超宽带传感的分辨率。这一建议的假设表明，这些改进将有助于无人值守的遥感人类和其他目标，通过更广泛的材料，而不牺牲扩展范围，分辨率和杂波抑制。这项工作将包括实地测量，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的不透明材料检测人类。前者对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，其中寻找人类主体的位置以及在墙壁、植被、雪、火、雾、黑暗、烟雾或其他不透明介质的另一侧检测可能的武器。后者包括地球物理勘探，矿体调查，公用事业检测和定位，路基和桥梁地下裂缝和空隙扫描，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.
