Data interface board of reconfigurable radar signal processing hardware platform

Abstract

The invention discloses a data interface board of a reconfigurable radar signal processing hardware platform, and belongs to the field of communications, the technical problem to be solved by the invention is how to meet the requirements of universalization, modularization and software of a radar signal processing system. The adopted technical scheme is as follows: the data interface board comprises an FPGA logic chip, an optical module, a gigabit PHY chip and a connector, PCB wiring between the FPGA logic chip and the optical module and between the FPGA logic chip and the connector meets therequirement that the maximum rate of each high-speed Lane reaches 10 Gbps, meanwhile, it is ensured that all differential pairs are equal in length and short in distance, and the signal transmission requirement is met; meanwhile, the FPGA logic chip supports storage of two groups of DDR4 memories, and the data transmission rate is 2400 Mb / s; the connector is connected with the gigabit PHY chip; wherein the FPGA logic chip is used for carrying out protocol conversion on data to enable the radar signal processing system to carry out data interaction with the outside so as to realize reconstruction of a data transmission mode of each port by the radar signal processing system; and the optical module is used for data interaction with the signal processing platform.

Description

technical field [0001] The invention relates to the communication field, in particular to a data interface board of a reconfigurable radar signal processing hardware platform. Background technique [0002] Traditional radar signal processing systems often adopt customized design ideas according to different application scenarios and specific functions. Although the designed hardware processing platform has high work efficiency, it is poor in flexible configuration and has little experience for reference, resulting in long development cycle and high cost. , low maintainability and other shortcomings, so the development of radar processing systems with ultra-high processing performance and fast interaction capabilities to meet the needs of functionally diverse radar systems has attracted widespread attention. Radar processing systems are also moving towards standardization, generalization, and modularization. , The direction of software development. [0003] At present, the g...
