    • A method and system for detecting the presence of subsurface objects within a medium is provided. In some embodiments, the imaging and detection system operates in a multistatic mode to collect radar return signals generated by an array of transceiver antenna pairs that is positioned across the surface and that travels down the surface. The imaging and detection system pre-processes the return signal to suppress certain undesirable effects. The imaging and detection system then generates synthetic aperture radar images from real aperture radar images generated from the pre-processed return signal. The imaging and detection system then post-processes the synthetic aperture radar images to improve detection of subsurface objects. The imaging and detection system identifies peaks in the energy levels of the post-processed image frame, which indicates the presence of a subsurface object.
    • 提供一种用于检测介质内的地下物体的存在的方法和系统。 在一些实施例中,成像和检测系统以多状态模式操作,以收集由跨越表面定位并沿着表面行进的收发器天线对阵列产生的雷达返回信号。 成像和检测系统预处理返回信号以抑制某些不良影响。 成像和检测系统然后从由预处理的返回信号产生的实际孔径雷达图像中生成合成孔径雷达图像。 成像和检测系统然后对合成孔径雷达图像进行后处理,以改善地下物体的检测。 成像和检测系统识别后处理图像帧的能级中的峰值,其指示地下物体的存在。

    • A system that detects damage on or below the surface of a paved structure or pavement is provided. A distributed road assessment system includes road assessment pods and a road assessment server. Each road assessment pod includes a ground-penetrating radar antenna array and a detection system that detects road damage from the return signals as the vehicle on which the pod is mounted travels down a road. Each road assessment pod transmits to the road assessment server occurrence information describing each occurrence of road damage that is newly detected on a current scan of a road. The road assessment server maintains a road damage database of occurrence information describing the previously detected occurrences of road damage. After the road assessment server receives occurrence information for newly detected occurrences of road damage for a portion of a road, the road assessment server determines which newly detected occurrences correspond to which previously detected occurrences of road damage.
    • 提供了一种检测铺设结构或路面表面上或下面的损坏的系统。 分布式道路评估系统包括道路评估舱和道路评估服务器。 每个道路评估舱包括一个地面穿透雷达天线阵列和一个检测系统,当安装荚的车辆沿着道路行进时,可以从返回信号中检测道路损坏。 每个道路评估舱将道路评估服务器传送到描述在当前道路扫描中新检测到的道路伤害的每次出现的发生信息。 道路评估服务器维护描述先前检测到的道路损坏事件的发生信息的道路损伤数据库。 在道路评估服务器接收到用于一部分道路的新检测到的道路损坏事件的发生信息之后,道路评估服务器确定哪个新检测到的事件对应于哪个先前检测到的道路损坏发生。
