UFO - Project description

...The UFO project aims at ensuring aviation safety at current high

standards or even better, regardless of air transport growth ...

Summary

Constrained by high update rate and accuracy requirements needed for wind measurements, 2D electronic scanning antenna technology based on low cost tile will be explored for X-band radar through a development of a tile mock up as well as a new high power laser source of 1.5 micron Lidar 3D scanner with higher power.

In addition, new design tools will be developed through simulators, able to couple Atmosphere models with Electromagnetic, Radar and LIDAR models. In parallel, advanced Doppler signal processing algorithm will be developed and tested for 3D wind field and EDR monitoring, including the algorithm for the resources management of the different sensors.

Comparison with already existing sensors as C band meteorological radar and S band ATC radar, but also ADS-B Downlink will be studied. Calibration of the ground sensors (Lidar, X-band radar, C-band radar) with ADS-B Downlink of meteorological data and the simulators will be achieved through a set of experimental trials in Munich and Toulouse airports. In Toulouse, an aircraft equiped with airborne probes will enable in situ comparison.

What kind of risk do we want to avoid

While the low altitude Wake Vortex Encounter is the main risk we are trying to tackle, all low altitude wind risks: wind gusts and wind shear should be managed by our system/sensors.
