Information and knowledge are actually well and easily distributed thanks to electronic journals, news, mailinglists and forums. It is however more difficult to deploy algorithmic and programming collaboration: the heterogeneity of the programming languages and the operating systems used by researchers constitutes a major problem to the design of a common(More)
A new spectral model of the return signal from a LIDAR Doppler wake vortex detector is proposed. It has been experimentally discovered during ground-based and flight test campaigns but suffered a lack of theoretical evidence. Using high resolution fluid simulations of wake vortices, we highlight the physical meaning of this model. Comparisons with the(More)
This paper describes the first successful attempt to detect wake vortices axially using an on-board infrared pulsed Doppler LiDAR (Light Detection And Ranging). On-board axial detection is more complex than the classic ground-based tangential approach, because the axial air speed in vortices is low and the atmospheric particle density is reduced, yielding a(More)
