中文摘要:
      声纳基阵信号模拟器是一种实用的、可近似仿真实际监测目标及使用环境的阵元级信号发生器。声纳基阵信号模拟器的使用将有效缩短数字式声纳的研制周期,大大减少湖试和海试的次数。文章中以通用信号阵列处理系统为运行环境,详细介绍了一种声纳基阵信号模拟器实时多任务系统的软件设计与开发过程,分析了该软件系统中所有基本任务的功能以及多任务之间的通信关系,并且最后给出了该实时多任务软件在通用信号处理机上的实现拓扑图。实践证明,该套软件功能完备,且具有很好的实时性和稳定性,非常适用于现代声纳工程领域。
英文摘要:
      A sonar array signal simulator generating signals received by hydrophones in a sonar array is useful in underwater acoustic engineering. It can simulate true detected targets as well as the ambience. Application of sonar array signal simulator can effectively shorten the process of digital sonar development, and decrease the time needed for experiments performed at sea. Therefore, study of sonar array signal simulator is important in the development of sonar technology. This paper introduces the process of software design and development of real-time multi-task systems of sonar array signal simulator based on the general-purpose signal-processing platform having a modular structure of hardware and a real-time operating system. The multi-task software is analyzed, including functions of all elementary tasks and communication between interrelated parts. The software is implemented and the topological structure is given based on the ADSP SHARC processors. The software has full functions. In addition, it shows good performance of real-time operations and high stability in applications. These good qualities make this sonar array signal simulator appropriate to be used in many fields of modern sonar engineering.
