Abstract
Japan aerospace exploration agency (JAXA) deals with unique approach of simulating aircraft noise and localizing moving source. It is composed of a microphone array and a jet propulsion unmanned aerial vehicle (JUAV). The microphone array on a runway combined with laser sensors, global positioning system (GPS), high-speed camera and so on enables the source localization of flying JUAVs. The JUAV were specially fabricated for simulating noise source such as engine, fuselage, high lift devices, landing gear and other probable aero-acoustic interference. This paper summarizes both the microphone array system and JUAVs developed in recent years.
