    Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and. Geophysical responses for more deeply buried sources decrease in amplitude and increase in spatial wavelength until respectively. In contrast, electrical and seismic methods can detect vertical, as well as lateral, contrasts of resistivity tailings and extent of acid mine drainage around mineral deposits (Dave and others, ).

    With the exception of wells and mine shafts drilled into Earth, direct observations of Earth’s interior are not possible. Instead, Earth scientists observe the interior of the planet using seismic waves, gravity, magnetic fields, radar, sonar, and laboratory experiments on the behavior of materials at high pressures and temperatures. Big Idea The Australian program in mine imaging was carried out under the Capability and Technology Demonstrator Program. The work on mine imaging was carried out by Midspar Systems in collaboration with DSTO. The aim of the program was to integrate advances in wide band technology to develop a system capable of detecting, localizing and classifying all mine types including stealth mines both on .

Sheetz Download PDF (6 MB)Author: Kraig E. Sheetz. Prior research on seismo‐acoustic sonar for detection of buried targets [J. Acoust. Soc. – ()] has continued with examination of various means for exciting interface waves (Rayleigh or Scholte) used to reflect from targets.

Several seismic sources were examined for sand beach applications, including vibrating shakers, shaker devices configured to preferentially excite.

Detection of buried underwater objects, and especially mines, is a current crucial strategic task. Images provided by sonar systems allowing to penetrate in the sea floor, such as the synthetic ape.

Especially for naval mine hunting, sophisticated techniques were developed for enhanced detection of buried targets by towed low-frequency arrays (Jans et al.

including the synthetic aperture sonar (SAS) approach (Piper ; Schock ) or 3D seismic systems (Vardy et al. The drawback is that those very high-resolution systems need to be towed and require sophisticated. J. Sabatierand N.

[1] The utility of acoustic‐to‐seismic coupling systems for land mine detection has been clearly established with potential as either a primary or confirmation sensor system.

They can detect very low metal content mines that are difficult for ground‐penetrating radar detection. For most applications, only the magnitude of the surface velocity is used to construct recognition algorithms. [21]. As part of mine detection, the distinction between the image of a mine and an object that physically resembles a mine is very complex and is relied on the recognition in shapes and textures.

Blondel [14]’s study combined two different advances in sidescan sonar applications [30], [31]. authors demonstrated that a buried object like a mine reflects a portion of seismic energy propagating along soil surface.

They suggested to utilize this reflection effect for landmine detection.

The objective was to advance current state-of-practices of geophysical. One promising method for buried mine detection, still in the early development stages, is the use of Seismo-Acoustic waves for target echo location. he goal of the research described in this thesis was to design and develop a four-element end-fire array to be used as a Seismo-Acoustic SONAR source to preferentially excite Rayleigh waves.

Advances in Sonar Technology the resolution remains quite low, especially for underwater minewarf are. SAS processing can then be used to artificially increase the length of the antenna and improve the resolution One of the purposes is the detection of objects buried in.

In military operations, the object is to rapidly clear a path through a minefield, and this is often done with devices such as mine plows and blast waves.

By contrast, the goal of humanitarian demining is to remove all of the landmines to a given depth and make the land safe for human use. Advanced Sonar Technologies for Autonomous Mine Countermeasures, Proceedings MTS/IEEE OCEANS, September T.

Hickey et al. () buried a plastic pipe at m depth using cut-and-fill and subsequently completed a seismic refraction survey orthogonal to the buried pipe. The authors noted reduced P-wave velocity (V P) around and above the pipe; however, the method of emplacement also disturbed the overlying material, which would be expected to.

For this reason the remote detection of buried explosive objects, surface-laid mines, and minefields is a key to the implementation of new Army warfighting doctrine based on rapid movement. Detection of mines and explosive objects to address Naval doctrine in the marine environment, whether in the surf zone, near-shore region, or in deep water.

The abundance and sheer variety of mine threats can also make detection more challenging. Some so called “bottom mines” can be buried or shallow-water mines easily triggered by surface ships or submarines. Moored mines, however, often tethered to the ocean floor, can be found in deeper parts of the water column.

[1] Buried land mines and chemical waste may provide the contrast in elastic properties within the soil needed to achieve detection via near‐surface seismic methods. The hazardous nature of these targets strongly indicates the use of noncontacting sources and receivers.

A home‐made ultrasonic parametric array allows us to insonify the soil with an intense beam of sound; this acoustic. The advances in surface-adaptive ground penetrating radar (GPR)-based anti-personal landmine detection project in Nagoya University is presented.
