A Design of Wireless Sensor Network Applied to Acoustic Localization of Supersonic Bullet

For the acoustic localization of of supersonic bullet, the traditional method is based on single-point centralized microphone arrays. Although there are many localization algorithms for single-point centralized microphone arrays at present, the caliber of single-point centralized detection is limited, resulting in problems such as small detection range, poor fault-tolerant performance and low localization precision. Application of multi-point distributed system to replace the current single-point centralized architecture for acoustic localization of supersonic bullet, which effectively compensates the defects of traditional monitoring. Aiming at the characteristics and requirements of wireless sensor network for acoustic localization of supersonic bullets, this paper studies the aspects of system composition, wireless sensor monitoring node, wireless sensor monitoring network and data fusion method. With the features of distributed and data fusion of wireless sensor network, accurate localization of the shooter is achieved.
