Homogeneous RF Field Distribution Optimization in 3T Abdominal Imaging

The appearance of severe signal drop-outs in abdominal Magnetic Resonance Imaging at 3 Tesla arises primarily from areas of very low magnetic flux density B1 of the transmit field in the body, and is problematic in both obese as well as very thin subjects. In this study, we show how thin patient-friendly pads containing new high permittivity...

Principles of the utilization of polarization-invariant parameters for classification and recognition of complex radar objects

The paper presents the first attempt to develop parameters that are invariant to polarization, aimed at classification and recognition of complex radar objects. Both the simplest (two-point) model and multipoint models of a complex object are analyzed using the so-called emergence principle and a generalization of the interference laws. The...

Beyond traffic depiction: Conformally integrating the conflict space to support level 3 situation awareness

The research described in this paper explores the addition of conformally integrated traffic probes into an egocentric Synthetic Vision (SV) Primary Flight Display (PFD). The underlying thought is that, although the traffic that is predicted to cause a future loss of separation may not lie within the field of view of the display, the location...

Exploring the potential of energy and terrain awareness information in a Synthetic Vision display for UAV control

This paper addresses the design and implementation of a conceptual Enhanced/Synthetic Vision Primary Flight Display format. The goal of this work is to explore the means to provide the operator of a UAV with an integrated view of the constraints for the velocity vector, resulting in an explicit depiction of the margins/boundaries of the multi...

Design of a synthetic vsion overlay for UAV autoland monitoring

For Unmanned Aerial Vehicles (UAVs), autonomous forms of autoland are being pursued that do not depend on special, deployability restraining, ground-based equipment for the generation of the reference path to the runway. Typically, these forms of autoland use runway location data from an onboard database to generate the reference path to the...

Using perspective guidance overlay to improve UAV manual control performance

The guidance information that is available to the UAV operator typically suffers from limitations of data update rate and system latency. Even when using a flight director command display, the manual control task is considerably more difficult compared to piloting a manned aircraft. Results from earlier research into perspective guidance...

Radar turbulence detection: Statistical synthesis and experimental check of adaptive algorithms
