Our Ground Penetrating Radar (GPR) has been in use since mid 2022. Since then Billy has visited over 40 cemeteries in 10 Kentucky counties and 3 Tennessee counties. He has found over 250 unmarked graves and 6 mass graves. The Society provides the service in return for a donation plus expenses.

The Matchless GPR-1, released in the 1990s, is an extremely well-regarded and rare tube preamp unit. It's rumored that only 30 of these were ever made, and was released just before the bankruptcy of the Matchless company. The GPR-1 is a 2-channel preamp that features four 12AX7/ECC83 vacuum tubes.

2014年11月15日 · GPR is a non-invasive geophysical technique that uses pulses of electromagnetic energy to provide a variety of information about the surface composition and subsurface structure, such as measuring dielectric properties and locating discrete targets within the subsurface (Slob et al., 2010).

2003年6月9日 · His final posting was to the GPR’s ‘A’ Squadron at Harwell. In early April, 1944, Major Griffiths, the Squadron CO, called the pilots together to tell them about a special mission which would...

RGPR is a free and open-source software package to read, export, analyse, process and visualise ground-penetrating radar (GPR) data. RGPR is written in R, a high-level programming language for statistical computing and graphics that is freely available under the GNU General Public License and runs on Linux, Windows and MacOS.

高斯过程回归，通常缩写为 GPR，是一种用于建模和预测函数的机器学习技术。 当您的数据不一定符合简单的线性或多项式方程而是遵循更复杂的模式时，它是一个强大的工具。

地质雷达（GPR）是一种非侵入性地球物理技术，用于检测和可视化地下物体。 GPR 系统向地下发射电磁波，并测量反射信号以识别地下结构。 由于其无需开挖即可提供详细的地下图像，这项技术广泛应用于建筑、考古和环境研究等领域。 GPR 通过发射高频无线电波脉冲到地下，通过发射天线来操作。 当这些波遇到电磁性质不同的材料（如管道、空洞或层界）时，部分波会反射回地面并被接收天线检测到。 测量反射信号返回所需的时间，并利用这些数据来确定地下特征的深 …
