Characteristics of a Current Amplifying Image Sensor with Buried Buried Electrodes

Buried Fiber Optic Intrusion Sensor

Buried Fiber Optic Intrusion Sensor. (May 2004) Eric William Maier, B.S., Texas A&M University Chair of Advisory Committee: Dr. Henry Taylor A distributed fiber optic intrusion sensor capable of detecting intruders from the pressure of their weight on the earth’s surface was investigated in the laboratory and in field tests. The presence of an intruder above or in proximity to the buried sensor...

Blast Mitigation Analysis of Semi-Buried Structure

Semi-buried structures are most commonly used at first line of defense along the border between two countries. This demands investigation of their dynamic behaviour under blast loading. Herein, a semi-buried structure with foam sandwiched walls and buttresses to reduce the effect of blast is analysed. The effect of provision of different configurations of buttresses and foam core between two la...

Radar Image of One Dimension Rough Surface with Buried Object

In order to detect a buried object quickly and accurately, a fast radar imaging method is presented in this paper. At first, complex backscatter data are computed by using propagation-insidelayer expansion combining the forward and backward method (PILE + FB). Then, a conventional synthetic aperture radar (SAR) imaging procedure called back projection method is used to generate 2-D image. The r...

Buried Landmine Detection with SERS

As of 1999, the only artificial systems employed by the U.S. military for the detection of buried landmines were metal detectors.1 Although these detectors can sense as little as 0.5 grams of metal, and thus maintain a high detection probability, they cannot distinguish between a firing pin or a piece of scrap metal. Furthermore, modern landmines can be constructed without metallic parts and wo...
