| 摘 要： | 反射是破坏信号完整性的原因之一。在充分考虑了反射的基础上,结合一种基于DSP和FPGA的雷达处理机的硬件设计,阐述了控制反射的具体方法。端接电阻和控制传输线长度可以控制反射。通过SpecctraQuest工具仿真得出的分析结果和实测结果,验证了该方案可以避免信号完整性的潜在影响。

| Abstract: | Reflection is one of the reasons of the destruction of signal integrity.Fully considered of reflection,then combined with the hardware design of the radar processor based on DSP and FPGA,the detailed solutions to control reflection are expatiated.Reflection can be controlled with the terminating resistor and the length of the transmission lines to be controlled.The simulation results by SpecctraQuest and the experimental results demonstrate that the scheme can avoid the influence of signal integrity. |
