PASSIVE LARGE BAND ACOUSTIC ACQUISITION DEVICES AND PASSIVE LARGE BAND ACOUSTIC IMAGING SYSTEMS.

摘要

A passive broadband acoustic acquisition device (3) capable of communicating with a digital processing unit, the device comprising a plurality of microphone sensors (7) capable of generating an electrical signal representative of a received acoustic pressure, a conditioning electronics and a digitizing electrical signals capable of adapting the electrical signals and transforming them into digital sound pressure signals, transfer electronics being able to communicate with a digital processing unit and enabling digital sound pressure signals to be transferred to the digital processing unit. The microphone sensors and the transfer electronics are mounted on a multifunctional rigid support member (17) incorporating the conditioning and digitizing electronics.
