3-D Ego-Motion Estimation Using Multi-Channel FMCW Radar

Yuan, S. (author), Zhu, S. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)

The problem of estimating the 3D ego-motion velocity using multi-channel FMCW radar sensors has been studied. For the first time, the problem of ego-motion estimation is treated using radar raw signals. A robust algorithm using multi-channel FMCW radar sensors to instantly determine the complete 3D motion state of the ego-vehicle (i.e.,...

Wave dissipation in a permeable structure: Experimental research on the physical processes causing energy dissipation inside an array of cylinders

Jansen, Wiljan (author)

Mangrove forests, which serve as a natural sea defence, have been degraded by human action during the last decades. To protect and recover these areas, different types of permeable structures consisting of bamboo have been proposed and applied. However, these structures are currently based on engineering judgement, as design rules are not...

Exploiting range migration for unambiguous velocity measurements

Blanco Campo, A. (author), le Chevalier, F. (author), Yarovoy, Alexander (author)

One of the most striking challenges that radar designers have to deal with, when developing new doppler systems, is to overcome the difficulty of working with ambiguous velocities. Even using high PRF’s, target’s velocities become ambiguous because wavelengths are getting shorter. This article tries to depict an idea of becoming unambiguous in...

Effects of electromagnetic forcing on self-sustained jet oscillations

Kalter, R. (author), Tummers, M.J. (author), Kenjeres, S. (author), Righolt, B.W. (author), Kleijn, C.R. (author)

The influence of electromagnetic forcing on self-sustained oscillations of a jet issuing from a submerged nozzle into a thin vertical cavity (width W much larger than thickness T) has been studied using particle image velocimetry. A permanent Lorentz force is produced by applying an electrical current across the width of the cavity in...

Experimental investigation of the flow inside a saxophone mouthpiece by particle image velocimetry

Lorenzoni, V. (author), Ragni, D. (author)

An experimental study of the flow inside a saxophone mouthpiece in playing conditions is carried out by means of particle image velocimetry at high acquisition rate. Planar velocity measurements on the midsection of a Plexiglas tenor saxophone mouthpiece are performed, respectively, in the mouthpiece baffle and in the reed channel. Sequences of...

Particle imaging velocimetry experiments and lattice-Boltzmann simulations on a single sphere settling under gravity

Ten Cate, A. (author), Nieuwstad, C.H. (author), Derksen, J.J. (author), Van den Akker, H.E.A. (author)

A comparison is made between experiments and simulations on a single sphere settling in silicon oil in a box. Cross-correlation particle imaging velocimetry measurements were carried out at particle Reynolds numbers ranging from 1.5 to 31.9. The particle Stokes number varied from 0.2 to 4 and at bottom impact no rebound was observed. Detailed...

Potential applications of laser anemometry for in-flight measurements

Jentink, H.W. (author)

This report concerns the application of laser anemometry for flight testing and other aircraft-related measurements. The laser anemometry technique and previous work in this field are reviewed and applications are described. A comparison of possibilities of laser anemometry with conventional techniques shows some unique advantages of laser...

Experimentele vortex analysator

van der Laan, J.M. (author)

A measuring system is described for detection and analyses of aircraft wake vortices in the approach zone of a runway. This system consists of propeller anemometers, a data-acquisition unit, a quick-look monitor and a NOVA minicomputer with a real-time vortex detection program. A short description of aircraft wake vortices is also given. Some...
