Project

X-WALD is funded by the European Commission under the Clean Sky JTI (Joint Technology Initiative, http://www.cleansky.eu/), call SP1-JTI-CS-2013-01, activity SGO (System for Green Operation).

 

X-WALD is a 18 months project which started in January 2014. 

 

In the framework of CLEANSKY Joint Undertaking (JU) European program and specifically in
the Clean Sky Systems for Green Operations (SGO) Integrated Technological demonstrator
(ITD), the use of a polarimetric avionic radar has been proposed in the Management of
Trajectory and Mission (MTM) study to have more precise information about not forecasted
weather phenomena. The goal is to optimize the skipping trajectories in order to minimize the noise pollution and emissions in each flight phase of the airplane.

 

To this purpose, two projects, namely CLEOPATRA and KLEAN, have been sponsored by the JU-SGO for developing an avionic polarimetric radar signal simulator (CleoSim) and the implementation and testing of polarimetric signal processing (AWR processing (AWRP), AWR post-processing (AWRPP)) and trajectory optimization algorithms (developed by Selex Galileo, now Selex Electronic System: SES) on an EFB (Electronic Flight Bag), respectively. An EFB is an electronic display system designed to replace the traditional pilot flight bag and to reduce or eliminate the need for paper and other reference materials in the cockpit.

 

The X-WALD specific objectives and their progress are summarized below:

 

  • Ob. 1 - X-BAND polarimetric radar overview, selection and acquisition. The radar must be suitable to be mounted on airborne platform for gathering data in presence of weather events in compliance with the JU-SGO goals.

 

  • Ob. 2 - Planning the ad hoc measurement campaign in well-monitored selected scenarios.

 

  • Ob. 3 - Experiments conduction and data acquisition.

 

  • Ob. 4 - Validation, optimization and SW refinement of the avionic polarimetric radar signal simulator (CleoSim).

 

  • Ob. 5 - Validation and optimization of the EFB weather radar signal processing and trajectory optimization algorithms (KLEAN project).

 

  • Ob. 6 - Refine the EFB GUI in accordance with the new needs resulting from the experimental data analysis.

 

  • Ob. 7 - EFB SW refinement and implementation to a level TRL5 (Technology Readiness Level 5).
