Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [1]

2024年5月8日 · Ground penetrating radar (GPR) is an electromagnetic geophysical method that transmits radio wave pulses at select center frequencies into the ground to study the subsurface. GPR capitalizes on the effects that the electrical properties of matter (i.e., dielectric permittivity, electrical conductivity, and magnetic permeability) have on ...

透地雷达（Ground-penetrating radar，缩写：GPR）是以雷达脉冲波探测地表以下状况并成像的仪器。 这是以无线电谱上的微波（UHF/VHF）波段电磁波进行的一种无损检测方式，并接收因为地表下各种物体结构造成的雷达反射波。

透地雷達 （Ground-penetrating radar，縮寫： GPR[1]）是以雷達脈衝波探測地表以下狀況並 成像 （英语：Geophysical imaging） 的儀器。 這是以 無線電譜 （英语：Radio spectrum） 上的 微波 （UHF / VHF）波段 電磁波 進行的一種 无损检测 方式，並接收因為地表下各種物體結構造成的雷達反射波。 透地雷達可以在岩石、土壤、冰、淡水、人行道以及各種結構物等介質使用。 透地雷達可探測到地表下的物質、材質變化、空隙和裂隙等 [2]。 透地雷達使用高頻率且通常被極化 …

Ground penetrating radar (GPR) offers an accurate, non-destructive solution to mapping the subsurface of the earth. Archaeologists and remote sensing specialists around the world rely on GSSI ground penetrating radar as a key tool for non-invasive site investigation.

Ground penetrating radar (GPR) is a non-destructive detection and imaging method which identifies subsurface elements either underground or within a surface such as concrete. According to the New York State Museum, GPR was invented in the 1930s as a tool for measuring the thickness of glaciers.

2007年1月1日 · Ground penetrating radar (also referred to as GPR, ground probing radar, or georadar) is a near-surface geophysical tool with a wide range of applications.

Ground-penetrating radar (GPR) uses a high-frequency (e.g. 40 to 1,500 MHz) EM pulse transmitted from a radar antenna to probe the earth. The transmitted radar pulses are reflected from various interfaces within the ground, and this return is detected by the radar receiver.

GPR is an electromagnetic (EM) geophysical method for high-resolution detection, imaging and mapping of subsurface soils and rock conditions. The idea of using the propagation of high-frequency EM waves for subsurface investigations can be traced back to the beginning of the century, but the earliest references to the possibility of using sharp ...

Ground Penetrating Radar (GPR) is a powerful subsurface exploration tool that uses electromagnetic waves to detect and map objects and structures beneath the ground's surface. GPR is useful for locating utilities because it detects what's beneath the surface without the expense and risk of digging or potholing .
