Penetration with Step Frequency Ground Penetrating Radar
where P is the transmitted power, τ is the integration time, Gt and Gr are the transmit and receive antenna gains, λ1 and λ2 are the longest and shortest wave lengths respectively, σ is the target radar cross section, R is the target range, k is Boltzmanns constant, T is the effective receiver noise temperature and B is the receiver bandwidth. In the case of GPR, the signal attenuation in the g...
متن کاملAdvanced Ground Penetrating Radar Signal Processing Techniques
Ground penetrating radar (GPR) is a non-destructive geophysical method that uses electromagnetic waves to image the subsurface. A typical GPR system has three main components: transmitter and receiver, directly connected to the transmitting and receiving antennas, and a control unit. Electromagnetic pulses are transmitted into the subsurface and the earth response is recorded. The GPR method is...
متن کاملFrequency-Dependent Attenuation Analysis of Ground-Penetrating Radar Data
I investigate the frequency dependence of attenuation and problems with measuring the intrinsic attenuation in reflection data. It is well established that in many materials attenuation is approximately linear with frequency over the bandwidth of the GPR signal, with a slope characterized by a constant Q* parameter. I show the relationship of Q* to the parameters describing Cole-Cole relaxation...
متن کاملGround-Penetrating-Radar Reflection Attenuation Tomography with an Adaptive Mesh
Ground-penetrating radar GPR attenuation-difference analysis can be a useful tool for studying fluid transport in the subsurface. Surface-based reflection attenuation-difference tomography poses a number of challenges that are not faced by crosshole attenuation surveys. We create and analyze a synthetic attenuation-difference GPR data set to determine methods for processing amplitude changes an...
متن کاملApplication of ground penetrating radar for coal depth measurement
This paper describes the development of a new ground penetrating radar system for measuring coal thickness in underground mining operations. Although subsurface radar exhibits significant potential for depth measurement, the raw signals are complicated and cannot be readily interpreted by mining personnel. We show how real-time digital signal processing plays a key role in transforming the raw ...
