FINAL REPORT Low-Cost Ultra-Wideband EM Sensor for UXO Detection and Classification

Low-cost Vector Network Analyzer for Biomedical Applications

A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...

A New Compact Ultra-wideband Linear Antenna Array for Target Detection Applications

This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3 GHz to 11 GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patt...

Multi-aspect detection of surface and shallow-buried unexploded ordnance via ultra-wideband synthetic aperture radar

An ultra-wideband (UWB) synthetic aperture radar (SAR) system is investigated for the detection of former bombing ranges, littered by unexploded ordnance (UXO). The objective is detection of a high enough percentage of surface and shallow-buried UXO, with a low enough false-alarm rate, such that a former range can be detected. The physics of UWB SAR scattering is exploited in the context of a h...

Classification of Magnetic Susceptibility Anomalies and Their Relevance to UXO Detection

The attention given the natural geologic background of a site and its influence on geophysical sensors has grown considerably over the past several years, primarily because of the governmentsupported unexploded ordnance (UXO) technology demonstrations and government mandated UXO cleanup activities. Explosive and ordnance detection (EOD) teams have encountered difficulties at sites thought to be...
