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.
