The Design Of High Speed Collection And Storage Board

With the rapid development of science and technology, data collection and storagesystem become a significant part of modern electronic system and it is widely used inradar fields. Gradually matured radar imaging system needs to obtain more information,so as to accurately determine the position, shape, motion and other parameters of theobject. In order to obtain a more accurate target information and higher imageresolution, we need high-speed collection and storage system in real-time recording ofdata to get faster data sampling rate and wider data bandwidth. High-speed, highsampling rate, large capacity, high-density, low power and low cost moderninformation collection and storage system is one important part of high-speed signaland information processing and other applications, which mainly include dataacquisition, storage and system control and management.A research on high-speed signal collection and storage board is introduced in thisthesis. Firstly, the selection of main chips and circuits design including the methodsand precautions are described. Then high-speed PCB design including prior knowledgeand detailed design process is introduced. Finally, the debugging of the board is shownand a summarization of the thesis was given.The main work of this thesis is as follows:(1) The design of high-speed collection and storage circuits is completed. Themodule of information collection and storage is achieved in a6U board.(2) The PCB design of high-speed collection and storage is completed.(3) The debugging of the board is compled and the rate that data transferred to theFLASH storage system can eventually be stabilized at320MB/s.
