| Abstract: | In order to meet the needs of radar signal acquisition in scientific research, the paper designs a multichannel data acquisition system based on FPGA. The system consists of the Ethernet interface of the MAC layer, DDR3 control of reading and writing, FMC interface of data access and control. Combined test of hardware and software shows that each function of data acquisition is good, and each channel is synchronous with small channel crosstalk. The system can be widely used in radar and communications fields. |
