Applications of unmanned vehicles can increase combat effectiveness and personnel safety. These include reconnaissance, surveillance, target acquisition, logistics, minefield and other obstacle detection, explosive disposal, physical security, and operations in contaminated environments. Better communication and GPS technologies are necessary for a convoy of unmanned vehicles to accurately foll...

This work provides a proof-of-concept for linear-position sensor using an ultrawideband (UWB) frequency-modulated continuous wave (FMCW) radar system operating at 126–182 GHz. It is the first to show environmental compensated and calibration-free distance measurements with micron accuracy medium range millimeter-wave (mmWave) technology. We addressed hardware imperfections, parameter estimation...

This paper presents a novel and robust algorithm that retrieves the rotation angle between two different patterns, together with their similarity degree. The result is optimal in the sense that it minimizes the euclidean distance between the two images. This approach is based on Zernike moments and constitutes a new way to compare two Zernike descriptors that improves standard Euclidean approac...

In this paper experimental comparisons between two Time-of-Flight (ToF) cameras are reported in order to test their performance and to give some procedures for testing data delivered by this kind of technology. In particular, the SR-4000 camera by Mesa Imaging AG and the CamCube3.0 by PMD Technologies have been evaluated since they have good performances and are well known to researchers dealin...

The problem of identifying clusters from MIMO measurement data is addressed. Conventionally, visual inspection has been used for cluster identification, but this approach is impractical for a large amount of measurement data. For automatic clustering, the multipath component distance (MCD) is used to calculate the distance between individual multipath components estimated by a channel parameter...
