Acoustic source two-dimensional localization was performed during flyover tests with an Airbus A340 in Tarbes, France, in 1997. The method combined a cross-shaped array of 29 microphones developed by ONERA to a D-GPS tracking system operated by Aerospatiale. These tests aimed to validate the method and evaluate its precision and performance. The si...
A new phased-array processing method has been developed to achieve accurate two-dimensional localization of acoustic sources. While conventional processing requires a full 2D array with an excessive number of microphones, the present method is designed for sparse arrays, and uses many fewer microphones. A cross-shaped array of 39 microphones was bu...

... It is employed by King [9] to analyse the noise distribution of high-speed trains. Howell et al. [10] and Piet et al. [11] also used the same algorithm to localize airplanes' sound sources. The acoustical holography method is proposed by Williams et al. [12] to track fixed sound sources and visualize sound fields. ...
... ■ Multiple arrays or known sound signals: Distributed microphone arrays have been used to localize (or triangulate) an unknown sound source, such as gun shots [63], wildlife [24], noise sources [55,70,71], and mobile devices [25]. Many works also address the inverse problem of localizing microphones with speaker arrays that are playing known sounds [13,15,42,50]. ...
