Abstract基于Casper硬件平台的射电望远镜数字系统正在被广泛应用.在Simulink中通过调用Casper模块可以实现复杂的数字信号设计,加快FPGA开发射电望远镜系统的效率.利用Casper模块和Simulink中Xilinx模块设计射电望远镜单元样机的数字信号处理单元,完成子带的抽取、下变频和整体频谱分析等功能.在Casper通用硬件平台ZYNQ7020上进行相关功能的仿真,验证了利用Casper模块和Xilinx模块设计基于FPGA的射电望远镜单元样机信号处理系统的可行性和高效性.
Other AbstractThe digital system of radio telescope based on Casper library is being widely used. In the Simulink, complex digital signal design can be realized by calling the Casper module. This module enables the development of signal processing functions in the Simulink graphical environment with the help of the System Generator tool, greatly improving the development efficiency of radio astronomy equipment. The Casper and Xilinx modules in Simulink are used to design the digital signal processing unit of the radio telescope unit prototype, and realize the sub-band extraction, down-conversion and overall spectrum analysis. The simulation of related functions are realized on the Casper general hardware platform ZYNQ7020, which verifies the feasibility and high efficiency for designing the digital signal processing system of radio telescope unit prototype based on FPGA by using Casper and Xilinx module.
