3D Modelling of Under Ground Burried Objects Based on Ground Penetration Radar

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...

Multi-Feature Based Multiple Landmine Detection Using Ground Penetration Radar

This paper presents a novel method for detection of multiple landmines using a ground penetrating radar (GPR). Conventional algorithms mainly focus on detection of a single landmine, which cannot linearly extend to the multiple landmine case. The proposed algorithm is composed of four steps; estimation of the number of multiple objects buried in the ground, isolation of each object, feature ext...

Multi-Feature Based Multiple Pipelines Detection Using Ground Penetration Radar

Ground penetrating radar (GPR) is one of the common sensor system used for underground inspection which emits electromagnetic waves that can pass through objects. The reflecting waves are recorded and digitized, and then, the images are formed. According to the properties of scanning object, GPR creates higher or lower intensity values on the object regions. Thus, these changes in signal repres...

Processing a multifold ground penetration radar data using common-diffraction-surface stack method

Recently, the non-destructive methods have become of interest to the scientists in various fields. One of these method is Ground Penetration Radar (GPR), which can provide a valuable information from underground structures in a friendly environment and cost-effective way. To increase the signal-to-noise (S/N) ratio of the GPR data, multi-fold acquisition is performed, and the Common-Mid-Points ...

Wire-grid electromagnetic modelling of metallic cylindrical objects with arbitrary section, for Ground Penetrating Radar applications

For any wire-grid model, a fundamental question is the choice of the optimum wire radius and grid spacing. The most widely used criterion to fix the wire size is the so-called same-area rule [2], coming from empirical observation: the total surface area of the wires has to be equal to the surface area of the object being modelled. However, just few authors have investigated the validity of this...
