In this paper a forward looking (end fire) synthetic aperture radar (SAR) system is described for the Very deep Autonomous Laser-powered Kilowatt-class Yo-yoing Robotic Ice explorer (VALKYRIE) project. Design and analysis of novel conformal log periodic antennas for the radar and the forward looking SAR ambuguity function is presented. Fabrication and laboratory characterization of the antennas system...

In this paper a forward-looking synthetic aperture radar (IceSAR) system is described for the ‘Very deep Autonomous Laser-powered Kilowatt-class Yo-yoing Robotic Ice explorer’ (VALKYRIE) project. Fabrication and laboratory characterization of novel log periodic antennas for IceSAR and system design and in situ testing of the synthetic aperture radar system are presented.
In this paper a log periodic folded slot antenna array is described for a forward-looking synthetic aperture radar (IceSAR) system for the ‘Very deep Autonomous Laser-powered Kilowatt-class Yo-yoing Robotic Ice explorer’ (VALKYRIE) cryobot project. Design and performance characterization of the log periodic antennas is presented along with a first light radar imagery obtained during in situ operation...
An inverted-F antenna with meandered line is characterized in this paper in terms of its proximity to the human body. Radiation characteristics are simulated and analyzed in the context of proximity of the antenna to human body tissue. The dependence of radiation characteristics like radiation pattern, resonant frequency, radiation efficiency, gain and front-to-back ratio; on the type & dimensions...
The electric grid in the US is aging and needs to be upgraded. Solutions involve the use of equipment with wireless communication capability for monitoring of generation, transmission and distribution. These systems introduce vulnerabilities to attack that can lead to blackouts and damage to equipment. In order to increase the reliability of the power systems, it is important to detect sources of...
