Design And Implementation Of Software Module Of Radar Signal Processing System Based On Zynq

With the continuous development of embedded application technology in the electronic information age,the embedded system based on traditional single chip microcomputer has been gradually inefficient and costly to face many complex problems.Programmable system-on-chip SOPC(System On Programmable Chip)as an efficient and flexible embedded system design solutions since then came into being.The content of this thesis comes from the design and implementation of the key IP core of a special digital signal processing.Pulse Doppler radar signal processor as the core part of the radar system,with complex processing,structural reusable,parameter configurable and other features,which makes the radar signal processor IP core function simulation and the overall prototype to achieve work Difficult to carry out.In this paper,based on the Xilinx Zynq series development board,this paper proposes a new method based on SOPC embedded system,which is based on SOPC embedded system.Design method of radar signal processing prototype of the overall realization of the program system for the software module design and implementation,making the radar signal processor design features are fully intuitive implementation and simulation,but also for the subsequent design improvement to lay the foundation.This paper first describes the development of embedded design technology and the development of Doppler radar and working principle,focusing on the SOPC design technology research significance and development trends.Secondly,this paper analyzes the work flow of Doppler radar signal processor,and makes an in-depth study on the architecture of Zynq series development board.Then,with the hardware and software collaborative design methodology,this paper presents the Zynq radar signal processing prototype as a whole to achieve the program and the system design of the software module framework,the system software module effectively through the software to complete the entire radar signal processing system Hardware part of the work control and parameter configuration.The whole module is divided into signal transmission and reception control and signal processing control two parts.Signal transceiver control part based on the Zynq series development board and AD9361 RF board to build the embedded software radio platform designed to drive and application,to achieve through the software control radar signal transceiver function.Signal processing part of the signal processing for the work process,combined with Zynq series development board architecture design advantages,the effective realization of the system hardware layer signal processing part of the work control and parameter configuration.Finally,the software module of the prototype system is designed and implemented,including the design of the system,the system layer and the application layer.The design of the driver layer includes DMA data transmission control,which mainly includes the signal transceiver module and the signal processing module,Signal processing part of the parameter configuration driver and the signal transceiver module SPI control driver design and implementation;system layer includes Zynq platform based on the establishment of embedded Linux system and Zynq QT operating environment on the building;application layer based on the design requirements of the system modular Design method implementation,including data transmission control module,parameter configuration module,data processing module and user interaction module four modules design and implementation.
