In this article, I propose a new method for calculating and visualizing the pulse radiation within depth range commonly used by Ground Penetrating Radar (GPR). The text describes illustrates propagation with several examples. One conventional is also applied quick comparison. can be to optimize GPR antennas transmit shapes.

OBJECTIVE The aim of this study was to investigate the effects of global postural re-education (GPR) on the treatment of spinal disorders by performing a systematic review and a meta-analysis. DESIGN MEDLINE, Scopus, and PEDro databases were searched without language or publication date restrictions. Data on pain and function were used to evaluate the effectiveness of GPR. Randomized controll...

The use of ground penetrating radar (GPR) for detecting the presence of near-surface interfaces is a scenario of special interest to the underground coal mining industry. The problem is difficult to solve in practice because the radar echo from the near-surface interface is often dominated by unwanted components such as antenna crosstalk and ringing, ground-bounce effects, clutter, and severe a...

Ground Penetrating Radar (GPR) has been used recently for diagnostics of the railway infrastructure, particularly ballast layer. To overcome fouling, mechanized cleaning process, which increases track occupancy time and cost, is usually used. Hence it crucial significance to identify at stage life cycle, level should be initiated. In present study, a series in situ GPR surveys on selected secti...

Traditional methods o f measuring tree root biomass are labor intensive and destructive in nature. We studied the utility of ground-penetrating radar (GPR) to measure tree root biomass in situ within a replicated, intensive culture forestry experiment planted with loblolly pine (Pinus tneda L.). The study site was located in Decatur County, Georgia, in an area of the Troup and Lucy (loamy, kaol...

Expression of a cAMP-specific phosphodiesterase in GnRH neurons in the GPR-4 transgenic rat resulted in decreased LH levels and pulse frequency and diminished fertility. We have characterized changes in fertility, adiposity, and reproductive and metabolic hormones with age. Although LH levels were decreased in 3-, 6-, and 9-month-old GPR-4 females relative to wild-type (WT) controls, GPR-4 fema...

Passive wireless transducers are used as sensors, probed by a RADAR system. A simple way to separate the returning signal from the clutter is to delay the response, so that the clutter decays before the echoes are received. This can be achieved by introducing a fixed delay in the sensor design. Acoustic wave transducers are ideally suited as cooperative targets for passive, wireless sensing. Th...

[1] Estimation of the three-dimensional (3-D) distribution of hydrologic properties and related uncertainty is a key for improved predictions of hydrologic processes in the subsurface. However it is difficult to gain high-quality and high-density hydrologic information from the subsurface. In this regard a promising strategy is to use highresolution geophysical data (that are relatively sensiti...

ENSCO, Inc. is investigating a novel approach to data fusion of magnetic and ground-penetrating radar (GPR) data to characterize previously detected buried targets. The method exploits a single model of the subsurface to predict both magnetic and GPR data observations. By determining the best single model that constrains both data sets, the optimum identification is computed. Using an a priori ...
