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.
