摘　　要：简述了多模引信声磁探测系统.通过声模块设计提出了一种比较适合单片机系统的频率提取方法,并对比了它与过零检测法和傅立叶变换的优缺点;通过磁模块设计提出了频率分析法,对比了在确定最佳炸点时与阀值法和能量比较法的优缺点;通过高速SOC单片机的设计完成了算法实现.从理论上分析和证明了频率提取法和频率分析法在本探测系统中的工程可行性.The concept, principle and main characteristics of sound and magnetic detection system are briefly introduced. An extracting method by frequency is presented which fits for the system of single chip microcomputer through the design of sound module, and is compared with zero-crossing detection method and Fourier transform. Frequency analysis is also presented and compared with the threshold method and energy comparing method in view of the optimum explosion time. The algorithm is realized through high-speed SOC single chip microcomputer. The feasibility of frequency extraction and frequency analysis is proved and analyzed.
