探地雷达（GPR）是一种无损测量技术，它使用电磁波来定位埋在视觉上不透明的物质或地球材料中的目标或界面。探地雷达也被称为地面探测、表面穿透（SPR）或地下雷达。探地雷达将一系列规则的低功率电磁能包发射到材料或地面中，并接收和检测来自埋藏目标的微弱反射信号。掩埋目标可以是导体、电介质或两者的组合。现在有许多商业上可用的设备，并且该技术在范围和能力上逐渐发展。探地雷达还成功地用于在刑事调查过程中提供法医信息，探测埋雷，勘测道路，探测公用设施，测量地球物理地层以及其他应用。关键词：探地雷达;电磁波
Ground penetrating radar (GPR) is a nondestructive measurement technique, which uses electromagnetic waves to locate targets or interfaces buried within a visually opaque substance or Earth material. GPR is also termed ground probing, surface penetrating (SPR), or subsurface radar. A GPR transmits a regular sequence of low-power packets of electromagnetic energy into the material or ground, and receives and detects the weak reflected signal from the buried target. The buried target can be a conductor, a dielectric, or combinations of both. There are now a number of commercially available equipments, and the technique is gradually developing in scope and capability. GPR has also been used successfully to provide forensic information in the course of criminal investigations, detect buried mines, survey roads, detect utilities, measure geophysical strata, and in other applications. Keywords: ground penetrating radar; ground probing radar; surface penetrating radar; subsurface radar; electromagnetic waves
