Ultrashallow Underground Imaging System For Detecting Buried Object Using Giant-Magnetostriciton Vibrator

Real-Time Vehicle-Mounted Multistatic Ground Penetrating Radar Imaging System for Buried Object Detection

Beamforming Array for Detecting Buried Land Mines

A beamforming array is investigated for use in a radar system that is part of a hybrid acoustic/electromagnetic technique for detecting land mines. The radar is used to measure the surface displacement of the earth due to acoustic waves in the earth. The beamforming array is used to obtain small spatial resolution for the measurement of the displacement while allowing an adequate stando distanc...

Buried Object Scanning Sonar for AUVs

A 252 channel FM sonar is developed to generate images of objects buried in sediments using reflection tomography. An omnidirectional source, transmitting FM pulses over the band of 2 to 12 kHz, illuminates buried targets. The backscattered signals are measured with 252 hydrophones and processed with a digital matched filter. Coherent nearfield focusing generates a 3D map of acoustic intensity ...

Detecting and locating leaks in Underground Water Mains Using Thermography

Water systems all over the world experience water losses. Leakage is the most common reason of water loss. Problems associated with water main leaks are a growing concern around the globe. These problems include water and energy loss, in addition to considerable properties damage. In current practice, not all water leaks can be detected due to intensive time and expensive cost associated with t...

Underground Neutrino Detectors for Particle and Astroparticle Science: the Giant Liquid Argon Charge Imaging ExpeRiment (GLACIER)

The current focus of the CERN program is the Large Hadron Collider (LHC), however, CERN is engaged in long baseline neutrino physics with the CNGS project and supports T2K as recognized CERN RE13, and for good reasons: a number of observed phenomena in high-energy physics and cosmology lack their resolution within the Standard Model of particle physics; these puzzles include the origin of neutr...
