Abstract

The impulse ground-penetrating radar (GPR) has a significant advantage than other radar systems, due to their high-resolution and simple system architecture. In this paper, a novel low-cost and compact impulse ultrawideband (UWB) GPR system is presented. The steep edged narrow pulse generation in the transmitter is solved with the step recovery diodes (SRD). In order to simplify the structure and improve the performance, a compact UWB antenna is employed which based on using of two smoothly shaped flares of a simple geometrical structure. Furthermore, the receiver employs a new ultra wideband digital sampling technology to realize analog-to-digital conversion instead of using commercial integrated ADC. This novel digital sampling technology is the first to employ both the successive-approximation-register technology and the equivalent-time-sampling technology to improve the sampling rate and the bandwidth of the receiver. Experimental GPR survey data obtained from different applications are presented. It is shown that the developed system has good ability for different detection applications.

一种新型小型超宽带探地雷达系统

脉冲探地雷达(GPR)具有高分辨率和简单的系统结构，与其他雷达系统相比具有显著的优势。提出了一种新型的低成本、紧凑的脉冲超宽带探地雷达系统。采用步进恢复二极管(SRD)解决了发射机中陡边窄脉冲的产生问题。为了简化天线结构，提高天线性能，采用了一种几何结构简单、形状平滑的两个信号源组成的紧凑型超宽带天线。此外，接收机采用了一种新的超宽带数字采样技术来实现模数转换，而不是使用商用集成ADC。这种新颖的数字采样技术首次采用了连续逼近寄存器技术和等效时间采样技术来提高采样率和接收机的带宽。介绍了不同应用下的探地雷达实验数据。实验结果表明，所开发的系统具有良好的检测能力。
