Research On Radar Targets' Detection And Data Acquisition System Based On USB

The background of this paper is one of the Tenth Five National Defense Technology main pre-research projects: the research of radar targets' detection and data acquisition system based on USB. it mainly researched how to realize the integration of targets' detection and data acquisition. Based on this technology, we have designed and made the detecting unit, the data acquisition unit, USB interface unit and controlling software, device driver, 8051' s program and so on.The chapter one is the preface. In the chapter a concise introduction is made to the background of this paper, the significance of the research, and in the mass every cell is also described.In the chapter 2 we introduce the targets' detection and data acquisition' s realization in detail, emphasize the critical technique, for example the algorithm of radar target detection, adding signs at the beginning of a frame data, forming the wave door, conversion of the data formal.In the chapter 3, a concise introduction is made to the USB specification. The principle of USB interface chip and the method to application are stressed. Two important concepts of interrupt and remunerate are discussed in details.In the chapter 4, the software designing of application program and 8051 program are introduced. The process of the standard device requests is also explained.In the chapter 5, first the characteristics of USB device driver underWINDOWS 2000 are introduced, then the composes of the driver is expounded. Atlast explicated how the driver communicates with the application. IOCTL control code is stressed here too.
