Design and Implement of Multi - DSP Artillery Acoustic Detection System

针对火炮发射阵地的侦察与探测,利用声学定位技术,设计并实现了一种基于TMS320C6713多片.DSP为核心的火炮声探测系统。提出了该系统的设计方案,说明了硬件电路的详细组成并进行了功能描述,重点阐述了以多DSP算法为核心的火炮声探测软件设计。本系统采用相关峰精确插值算法(FICP)和优化线性调频Z变换(MCZT)算法,提高目标时延估计,采集气象信息对时延差进行修正,有效实现了对火炮发射波、爆炸波的特征提取和定向。在实际使用中验证了系统的可靠性和探测精度。

Aiming at scout and detection of artillery bastion, a Artillery Acoustic Detection System（AADS） based on multi - DSP of TMS320C6713 with the technology of acoustic localization is designed and implemented. The design of AADS is intro- duced, the details of hardware circuit design and circuit function are discussed, algorithm based on muti - DSP is core of AADS software design which is highlighted. By using the Fine Interpolation Correlation Peak （FICP） and Modified Chirp - Z Transform （MCZT） algorithms to increase accuracy of time -delay estimation ,meanwhile a modification of time -delay taken effect by calculating meteorologic information, AADS classifies the directions and characteristics of artillery shooting sound wave and exploding sound wave effectually. Implementation of AADS proves that the AADS has high accuracy and reliability.
