摘　　要：基于计算机仿真技术,提出了一种新的低功耗、便携式声纳目标模拟器的设计方法。建立了水下目标回波的仿真模型,使用VC开发程序产生回波数据,通过计算机PCI总线输出到外围硬件系统。给出了目标模拟器的设计参数和硬件结构,验证系统设计的实时性。给出DMA工作方式下数据传输的设计方法,可编程逻辑器件的控制逻辑和驱动程序设计,解决了数据传输连续性的关键问题。通过与声纳系统的联调实验,证明该设计能够满足声纳系统的需求,显示出该设计广阔的应用前景。A new design of sonar target simulator which uses computer simulation technique is proposed. The design has peculiarities such as portability and low power consumption. An underwater target echo model is established and the program is developed in Visual C ＋ ＋ environment to generate echo data. The echo data is transmitted to periphery hardware system through PCI bus. Hardware structure and main technical parameters are discussed and the real-time design is validated. The way of data transfer in DMA mode, control method of logical programmable device and design of driver program are discussed to solve the key point of sequential transmission. After the manipulation with sonar system, the sonar target simulator is proved to be reliable and the abroad application foreground is shown.
