SIGNAL PROCESSING METHOD FOR CONFORMAL SURFACE MICROPHONE ARRAY ACOUSTIC DETECTOR USING PLANE WAVE MODEL, STORAGEE MEDIUM CONTAINING SIGNAL PROCESSING PROGRAM FOR CONFORMAL SURFACE MICROPHONE ARRAY ACOUSTIC DETECTOR USING PLANE WAVE MODEL, AND CONFORMAL SURFACE MICROPHONE ARRAY ACOUSTIC DETECTOR WITH SIGNAL PROCESSING PROGRAM FOR ACOUSTIC DETECTOR USING PLANE WAVE MODEL

摘要

PURPOSE: A signal processing method is provided to reduce detection errors due to the increase of an arrangement density when a curved arrangement is mapped to a reference plane. CONSTITUTION: An acoustic signal acquiring part includes a curvedly arranged microphone array. An acoustic signal processing part processes an acoustic signal which is obtained from the acoustic signal acquiring part(S100). An arrangement acoustic signal, in which a weighted value is applied, is added(S130). A display part displays the processing result of the acoustic signal processing part(S140). The acoustic signal processing part forms an arithmetic processing part in order to operate a storage media and a program.
