【摘要】 以声学法作为检测手段,构建基于MCU与ARM双核架构的弹着点定位系统。其由前置处理、无线传输、信号处理、定位评估等子系统组成。采用小波分析技术,利用Matlab设计系统炸弹爆炸后的声音信号分析算法,并用VC编写软件包。系统还考虑复杂的外界环境因素对检测结果的影响,并采用无线微波网络技术传输数据信息。更多还原

【Abstract】 This paper establishes a location system of impact point through dual-core architecture based on MCU and ARM,by means of acoustics detecting technique.The system is composed of subsystems like pre processing,wireless transmission,signal processing and location evaluation.We used wavelet analysis technology to design analysis algorithm of sound signals by MATLAB,and programmed software package by VC.The system transfers information by means of microwave radio network technology,considering the influence of complex external disturbance on detection results.更多还原
