This Small Business Innovation Research project will apply recent advances in ground probing radar (GPR) technology to the aerial reconnaissance of underground facilities (UGF). Ground probing radar is a proven technology for investigating subsurface targets and structures. Its application to subsurface monitoring from airborne platforms, however, has been limited due to clutter and signal strength problems. The project seeks to overcome these problems by the use of a beamsteered antenna array that provides increased signal power and increased angular resolution. The system will ultimately be suspended from an airborne platform to facilitate rapid coverage of a region of interest (ROI). The narrow transmit array beam scans the ROI, and at the correct angle of incidence a strong reflection from the UGF is received. The phase I project comprises three main tasks: first, simulating the proposed system; second, using the results of simulations to refine existing array control algorithms, and; third, testing the hardware prototype. A large part of the effort lies in software development in simulations and algorithm refinement. The results of Phase I will be used to develop and test a commercially marketable GPR system during the phase II effort. If the technology can be successfully developed, it will make airborne detection of near-surface UGFs in realistic environments feasible. The system is designed to enhance existing commercial GPR systems and will greatly reduce the cost of data acquisition of areal targets while enhancing data quality. The dynamic monitoring aspect of the instrumentation is unique and has application from the standpoint of characterizing extensive hazardous waste sites numbering in the thousands across the United States. This option will provide a low-cost alternative to invasive monitoring techniques.

这个小型企业创新研究项目将把地面探测雷达（GPR）技术的最新进展应用于地下设施（UGF）的空中侦察。地面探测雷达是一种用于调查地下目标和结构的成熟技术。然而，由于杂波和信号强度问题，其在机载平台地下监测中的应用受到限制。 该项目试图通过使用波束控制天线阵列来克服这些问题，该天线阵列提供增加的信号功率和增加的角分辨率。 该系统最终将悬挂在空中平台上，以促进对感兴趣区域（ROI）的快速覆盖。 窄发射阵列波束扫描ROI，并且以正确的入射角接收来自UGF的强反射。 第一阶段的项目包括三个主要任务：第一，模拟拟议的系统;第二，使用模拟的结果来完善现有的阵列控制算法，以及;第三，测试硬件原型。很大一部分工作在于模拟和算法改进中的软件开发。第一阶段的成果将用于在第二阶段的工作中开发和测试一种可商业销售的GPR系统。如果该技术能够成功开发，它将使在现实环境中进行近地表UGF的空中探测变得可行。 该系统旨在加强现有的商业探地雷达系统，并将大大降低区域目标数据采集的成本，同时提高数据质量。 该仪器的动态监测方面是独特的，从表征美国各地数以千计的广泛危险废物场地的角度来看，具有应用性。 这一选择将为侵入性监测技术提供一种低成本的替代方法。
