【摘要】 传统的声呐设计,采用专用硬件配以专用软件实现实时信号处理,开发周期长,可靠性可维修性较低。利用通用信号处理平台实现数字声呐设计是今后的一种发展方向。分析了数字声呐设计的基本原则,研究了一种利用通用信号处理平台实现传统数字声呐的仿真设计方法。分析了通用信号处理平台的总体设计、硬软件组成及功能特点,利用该平台,按照50%冗余设计,完成了48路圆柱型基阵主动声呐的实时仿真设计。通过该仿真设计实例,说明数字声呐可以方便地采用通用信号处理平台来实现。更多还原

【Abstract】 Development of conventional sonar takes a great deal of efforts and has a low reliability due to the involvement of various special-purpose hardware and software. Design of digital sonar using general signal processing platform (GSPP), on the other hand, provides a way to solve these problems in the future. The design consideration, hardware and software constructions, characteristics and ability of the GSPP are analyzed and described. Real-time simulation of active sonar design with a 48 channel cylindrical array and 50% redundancy is carried out using four DSP boards on GSPP. We conclude that the digital sonar can be realized conveniently by means of GSPP.更多还原
