| Abstract | 为同时完成4个Stokes矢量参数的相关测量,反演海面风场,提出了新型数字相关器的设计方法。结合高速数字相关器在数字极化辐射计中的应用,介绍了高速数据采样和相关处理系统。通过两片高速A/D转换器(ADC08D1500)同步采样四路信号,采样结果通过Xilinx公司新一代现场可编程门阵列(FPGA)-Virtex5芯片作相关运算,相关结果通过串口上传到计算机,详细介绍了系统各个部分的接口电路和时序控制的设计。系统可以实现四路信号最高1.5GHz采样率的相关计算。 |
| Other Abstract | To get all the four Stokes parameters and ocean surface field,a novel digital correlator used in polarization radiometer is introduced.Two high-speed A/D converter(ADC08D1500)are used to sample four signal channels at the same time.The sampling results are operated in the newest field-programmable gate array(FPGA)-Virtex5 made by Xilinx to make correlation calculation with correlation results translated to computer by serial port.The design of interfacing circuit and control system of the main modules are presented in detail.The system max sampling rate is 1.5 GHz. |
