Development of Pulsar Digital Backend Based on RFSoC
文献摘要：
Radio Frequency System on Chip(RFSoC)offers great potential for implementing a complete next generation signal processing system on a single board for radio astronomy.We designed a pulsar digital backend system based on the ZCU111 board.The system uses RFSoC technology to implement digitization,channelization,correlation and high-speed data transmission in the Xilinx ZU28DR device.We have evaluated the performance of the eight 12-bit RF-ADCs,which are integrated in RFSoC,with the maximum sampling rate of 4.096 GSPS.The RF-ADC sampling frequency,channel bandwidth and time resolution can be configured dynamically in our designed system.To verify the system performance,we deployed the RFSoC board on the Nanshan 26 m radio telescope and observed the pulsar signal with a frequency resolution of 1 MHz and time resolution of 64 μs.In the observation test,we obtained pulsar profiles with high signal-to-noise ratio and accurately searched the DM values.The experimental results show that the performance of RF-ADCs,FPGA and CPU cores in RFSoC is sufficient for radio astronomy signal processing applications.
