Improved magnetic STAR methods for real-time, point-by-point localization of unexploded ordnance and buried mines

Autor: J. Oeschger, Kwang Lee, R. Wiegert

Publikováno v: OCEANS 2008.

There is a pressing need for a practical and effective magnetic sensing technology that can be deployed onboard highly maneuverable sensing platforms and used for real-time, point-by-point detection, localization and classification (DLC) of magnetic

Demonstration of a Novel Man-Portable Magnetic STAR Technology for Real Time Localization of Unexploded Ordnance

Autor: John Oeschger, R. Wiegert, E. Tuovila

Publikováno v: OCEANS 2007.

We report results of field tests of the first prototype of a novel man-portable Magnetic Scalar Triangulation and Ranging (STAR) technology. The new magnetic sensor system technology is being developed with support from the Strategic Environmental Re

Generalized Magnetic Gradient Contraction Based Method for Detection, Localization and Discrimination of Underwater Mines and Unexploded Ordnance

Autor: J. Oeschger, R. Wiegert

Publikováno v: Proceedings of OCEANS 2005 MTS/IEEE.

We report significant progress toward full development of a unique magnetic-gradient-tensor-based "scalar triangulation and ranging (STAR)" method for detection, localization and classification (DLC) of magnetic targets. The STAR method converts magn

Theoretical models of the impact of climate change on natural populations, communities and ecosystems. Final report, 1989--1992

Autor: R. Wiegert

Land use change is a relatively understudied aspect of global change. In many cases, the impact of land use on plant and animal species may be far greater than the impact of climate change per se. As an integral part of our long-term studies of the r
