, Validations measurements has shown the possibility of our algorithm to analyze rotating sources, and to separate stationary of rotating ones. The test case on a "in duct fan", has shown its capability to correctly track a high speed fan. For further analysis on such device, green functions (in free field condition in our application) has to be estimated closer to the real environment
