本文介绍了针对高速公路路面和桥面检查的双通道、空气耦合超宽带（UWB）探地雷达（GPR）的开发。与大多数现有的单通道和低测量速度的GPR相比，我们的GPR具有竞争力的功能，包括宽区域覆盖，高空间分辨率和在正常公路行驶速度（高达60英里/小时）下的操作能力。该系统具有双通道微波前端、高速（8 Gsps）真实的实时数据采集单元、高吞吐量多线程数据传输和存储模块以及在现场可编程门阵列（FPGA）中开发的定制的低成本控制元件。不同的钢筋实验建立GPR系统的性能。
This paper presents the development of a dual channel, air coupled Ultra-Wideband (UWB) Ground Penetrating Radar (GPR) targeting highway pavements and bridge deck inspections. Compared to most existing GPRs with a single channel and low survey speeds, our GPR possesses competitive features, including wide area coverage, high spatial resolution and operating capability at normal highway driving speed (up to 60 mph). The system has a two-channel microwave front end, a high speed (8 Gsps) real time data acquisition unit, a high throughput multithread data transmission and storage module, and a customized low-cost control element developed in a field-programmable gate array (FPGA). Experiments with different steel reinforcing bars establish GPR system performance.
