The wideband radar intermediate frequency direct acquisition module is used to acquire, process and transmit data, which is an important part of radar system. Based on the current advanced Virtex‐7 FPGA board and high‐speed ADC card, this article designs the module from two aspects of hardware design and hardware development, including structure design, data flow design, and FPGA top‐level design. Then the article researches on some key technologies involved, including JESD204B protocol configuration, data flow transmission, DDR3 buffer design and clock optimisation. Practice has proved that the design of this article can accomplish the task well in practical engineering.
