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

The signal processing method for the invention sonar using plane wave model, ; a) step of acquiring the sound signal from a plurality of microphones arranged curved surfaces are arranged (S100) and; ; b) by a distance difference between a collimated virtual straight line arrangement direction of the curved array, and in particular the phase delays or antecedence, and step (S110) for calculating the equivalent linear array acoustic signal from the surface acoustic array signal; ; c) and multiplying the equivalent weight of a linear array of acoustic signal equalizing arrangement according to the arrangement density on the imaginary line when the spirit sikyeoteul surface arranged in the virtual line (S120); ; d) wherein step (step of summing the weighted linear array of acoustic signal obtained in S120) (S130) and; ; e) by summing the specific direction in the above step (S130) displaying to calculate the power of a linear array of acoustic signal (S140); for sonar signal having a sonar signal processing method and an arrangement of a microphone array having a curved surface arranged in a microphone array, characterized in that configuration, including treatment programs will have on the sonar has a built-in storage medium, and a curved array microphone array.
