Abstract

The invention provides an FPGA chip data processing method, a chip, computer equipment and a storage medium, and belongs to the field of radar AD front-end digital processing. The method particularlycomprises the following steps: receiving serial sampling data of a digital-to-analog conversion module by adopting a JESD universal interface, the sampling frequency of the serial sampling data beingnot less than 200MHz; converting the serial sampling data into multiple paths of parallel data through an IP core of the JESD universal interface; respectively carrying out frequency mixing processingon the multiple paths of parallel data by adopting a digital control oscillator to obtain frequency mixing data corresponding to each path of parallel data; and performing filtering processing on each group of frequency mixing data to obtain low-frequency digital-analog sampling data. Through the processing scheme disclosed by the invention, the FPGA chip is simple in design, strong in processingcapacity and easy for engineering practice.

Description

technical field

[0001] The invention relates to the field of radar AD front-end digital processing, in particular to an FPGA chip data processing method, chip, computer equipment and storage medium. Background technique

[0002] The radar AD front-end preprocessing system is an important part of the radar system, which mainly completes the functions of intermediate frequency signal reception and baseband signal conversion. With the development of active phased array radar to large bandwidth and high integration, the system puts forward higher requirements for digital components, and light weight, small size and high bandwidth have become its important development trend. The traditional AD front-end preprocessing has the following disadvantages: when the parallel bus is used to communicate with FPGA, there are many output pins, which leads to the difficulty of PCB layout and the increase of design cost; DDR and SDR interfaces are used in FPGA, the communication bandwidth is l...
