【摘要】 基于PCI总线的通用信号处理机能够充分发挥数字信号处理器和PCI总线的优势,满足雷达信号实时处理、传输的要求,在现代雷达信号处理中得到广泛应用。但是,通用信号处理机的尺寸难以满足雷达小型化的要求,为了实现LFMCW雷达小型化,研制基于PCI总线的嵌入式信号处理机十分必要。为SAR雷达回波模拟器设计专用的PCI总线接口,满足其信号处理机对系统控制、数据传输的要求,同时增强其通用性,具有积极的作用和意义。本文通过对以上两种雷达信号处理机的设计开发过程,研究了采用多片DSP信号处理器组建并行处理模块实现信号处理算法的方法,利用PCI总线实现处理机数据传输接口,设备驱动程序和控制界面软件开发,实现信号处理机数据传输控制等几个方面的内容,主要工作如下:1)针对线性调频连续波雷达信号处理算法,完成了基于PC104-PLUS总线的嵌入式信号处理板的设计、制作以及调试。2)根据SAR回波模拟器信号处理机的对系统控制、数据传输的要求,完成了该系统PCI接口设计的阶段性任务,完成了接口FPGA程序的逻辑设计与仿真。3)完成了SAR回波模拟器信号处理机驱动程序设计、编写以及调试。4)根据SAR回波模拟系统的功能要求与PCI接口设计,设计编写了该系统控制测试软件,在开发板上完成了用户软件主要功能的调试。调试结果表明,以上研制的雷达信号处理机、PCI接口逻辑、驱动程序与控制界面程序均满足系统设计的要求,能够实现系统的正常运行。更多还原

【Abstract】 Because the general signal processing system based on PCI bus making use of advantages of the DSP and PCI bus, can meet the high level demands of the radar signal processing and data transfer ability, so it’s application in radar system are developed rapidly.But the general signal processing system based on PCI bus can not meet the size demand of the LFMCW radar system miniaturization. So development of the LFMCW radar signal processing system based on the embedded PCI bus is necessary; Designing special PCI bus interface, not only meet the system control、data transfer requirement of the SAR raw-data simulation system, but also make the system general.In the thesis, based on design and implementation of the two signal processing system of different requirement, Multi-DSP processor structure, DSP-PCI Interface, system control logic, PCI device driver program, user application program are researched. The main content is list as follows:1) According to the LFMCW radar signal processing algorithm, a signal processing system based on PC104-PlUS bus is developed. Accomplishing the system design、hardware implementation and test;2) According to the simulation algorithm of the SAR raw-data simulation system, Accomplishing the design and simulator of the system’s DSP-PCI bus interface.3) Accomplishing the development of the driver programs for two signal processing board.4) Accomplishing the user application of the SAR raw-data simulation system.更多还原
