The following topics are dealt with: sea clutter; imaging radar; multifunctional systems; maritime radar; multichannel systems; MIMO radar; meteorological radar; FMCW radar; radar signal processing; ultra wideband radar; SAR processing; airborne radar; and radar antennas.
To assess maturity and capability of X-band radars to monitor wake roll-ups in all weather conditions, Radar data were collected on airports, near runway at ORLY airport and just under its ILS Interception Area. Additional trials took place on Paris-CDG Airport to benchmark Lidar & Radar Technologies. Continuous Detection, characterization and profiling capabilities of wake vortices, up to a range...
A method for modeling and tracking convective clouds within radar images is presented. An object modeling approach is used, based on the extraction of either morphological or grayscale skeletons from 2-dimensionnal cross-section of 3-dimensional radar data. Grayscale skeletons are appropriate shape descriptors for non-rigid and heterogeneous objects, in which gray-level local maxima correspond to...
The method using geostationary satellites to determine hydrometeors parameters and to diagnose hazardous occurrences, such us: showers, hail formations, lightings, turbulences, etc are presented. The advantage of the multiposition bistatic radar system is a capability of detecting small objects (turbulences) owning to a sharp increase in the value of Radar cross-section of objects close to base line...
This paper studies the relationships between recently introduced differential Doppler velocity and other parameters of radar signal reflected from rain. Analytical calculation and simulation methods are used mostly. The results are checked by measurements in special cases. Some possibilities to derive information on distributed object structure are shown.
An integrated target/weather surveillance at medium range, i.e. for the Terminal Manoeuvre Area (TMA) in the frame of Air Traffic Control (ATC) and regional weather monitoring, is made possible by MPAR (Multifunction Phased Array Radar) techniques, allowing a single technology to satisfy different requirements. The guidelines for system design, needed for cost/benefit analysis, were described in a...
Mesoscale numerical weather prediction models coupled with modern parabolic equation radar performance models have allowed the resolution of four dimensional radar performance in challenging non homogeneous near surface refractivity fields at the time and location of the modeller's choice. Large scale offshore flow of warm and dry air over colder seas produces strong surface ducting. Large land-sea...
