Abstract

Abstract: In order to study the angle tracking problem of 3D dynamic acoustic array for two-dimensional acoustic target under the interference of point acoustic source, the basic principle of multi-source interference was analyzed, and a mathematical model of angle tracking pointing performance of dynamic acoustic array under the interference of dual acoustic sources was established. The angle tracking pointing performance of dynamic acoustic array under the interference of point acoustic source was analyzed based on the acoustic signal characteristic difference between Pseudo target and real target, so the relationship between its angle tracking pointing performance and the interference factors were obtained. Finally, the evaluation indicator of angle tracking pointing performance under the interference of point acoustic source also was established based on the hypothesis of equal power under the interference of dual acoustic sources .

Key words: information processing, 3D dynamic acoustic array, angle tracking, dual acoustic source, pointing performance, angle deflection index
