Wake vortex detection & monitoring by X-band Doppler radar: Paris Orly radar campaign

TL;DRAbstract

In order to improve the capacity of airports to handle the expected increasing amount of traffic, the knowledge about the safety issues for wake vortexes mitigation has to be improved. Currently, safety distances are very conservative and depend only on category size of aircrafts, without taking into account local wind nowcasting. The final goal is to develop a wake vortex alert system for controllers to ensure operationally in all weather conditions adaptive appropriate not oversized separation rules. In a first step, it is necessary to perform long time data collections of wake vortex sensor signature on large European airports. For the time being, Lidar sensors has been used to collect data on wake turbulence and deliver accurate measurements, but their uses is limited to clear air conditions and are not operational in rain & fog weathers. On the other hand, radar is a good complementary sensor, which can be used for turbulence remote sensing as well. To mature this last solutio
