The localization of buried targets using Ground Penetrating Radar (GPR) is dealt with. The bi-static GPR is made of two identical Vivaldi antennas operating from 0.5 GHz to 3.5 GHz and installed in front of a sand box. The experimental data acquired in a controlled laboratory environment are validated by electromagnetic simulation. Then, both synthetic and experimental data are processed to detect...
The clutter removal is a vital procedure in the target detection with Ground-Penetrating Radar (GPR). In this paper, we present morphological component analysis (MCA) based clutter removal method adapted to the migrated data. Firstly, the received B-scan data is migrated by using phase-shift migration method. In the migrated B-scan, the clutter appears as horizontal stripes and the hyperbolic reflecting...
There have hand-held GPR systems and vehicle-mounted GPR systems, which are offset from the air-ground interface by a nonnegligible distance, developed for landmine detection. Vehicle-mounted systems have exclusive advantage that can show subsurface imaging in horizontal slices based on grid GPR data set. Hand-held GPR system is one of advantageous technologies in mountain district etc. But handheld...
Estimation the shape and position of the objects is an important subject in ground penetrating radar(GPR). Migration method in domain of seismic techniques is effective to locate and reshape the objects. Kirchoff migration method is based on electromagnetic wave equation. It is an accurate calculation method. Kirchoff migration method has widely adaptabilities with different horizontal and vertical...
GPR is a geophysical method which uses electromagnetic pulse radiation to make the image of subsurface and objects in it. The main advantage of the method is that it is nondestructive method. In this paper we proposed to use transformation of coordinates from iGPS system to GPS format for synchronization measurement traces and it coordinates in the RAMAC system. The experimental data was processed...
Practical GPR survey schemes based on a geometrical migration algorithm are implemented and experimentally tested: (1) random GPR data collection from water surface along a tangled path and interpolation to a regular grid for bottom reconstruction; (2) double-pass B-scan with different antenna offset for estimation of the upper ground layer thickness and permittivity. An analytical relation between...
SoftMan is a software artificial life and migration is one of its attributes. Through analyzing the format and load process of ELF file, checkpoint mechanism of Linux is made use of in this paper and designs the algorithm which integrates static migration and active migration of SoftMan. In the environment of LAN, a method of SoftMan migration based on rebuilding the Linux kernel is designed and implemented...
Ground penetrating radar (GPR) is a promising sensor for landmine detection, but there are two major problems to overcome. One is the non-planer (e.g. rough and/or undulating) ground surface. It remains irremovable clutters on a sub-surface image output from GPR. Geography adaptive scanning is useful to image objects beneath non-planer ground surface. The other problem is the distance between the...
