【Abstract】 As the key testing instrument, the use of Sonar Target Simulation System not only can shorten the research period of sonar greatly, but also play a significant role in sonar production and application. Based on mathematic model of actual target system, the system of sonar target simulation compute the emulational data, and send it to the peripheral equipments through hardware units, assisting sonar designer and maintainer for testing and researching actual sonar system.This dissertation discusses the design and project realization of system hardware and application software detailedly about some dipping sonar target simulation system. PCI Bus is a high-powered 32/64 bit bandwidth address/data alternate local bus. This project develops dipping sonar target simulation system based on PCI Bus in virtue of its high speed and CPU-independent performance. The content of this dissertation involves these aspects:1. It introduces the principle of ecumenic sonar and some dipping sonar, analyses the function and common structure of target simulation system, establishes the mathematic models and simulation algorithm such as noise radiated by target, sonar array and target echo.2. To satisfy the application requirement of some dipping sonar, it researches high speed data transmission based on PCI Bus protocol thoroughly, designs the hardware platform using PCI Bus and the programmable logic component, and develops corresponding application software.3. For the engineering realization, it lists the outline of design points about schematic and PCB document in the development of PCI equipment, gives the design scheme of power supply suiting for laboratory and outfield, designs system based on industrial computer model which minishes the system scale greatly.4. It gives debugging scheme of system hardware and software, points out the solutions of the problems encountered, and carries through performance testing to the system.The results of testing and application demonstrate that the system could achieve technical requirement of actual application primely, actualize the test of sonar performance completely. By using the PCI Bus technique and the large scale更多还原
