Design Of Programmable Radar Signal Synchronization System By FPGA

With modern electronic information technology continues to evolve, modern radarsystems require increasingly large amount of data processed, the mode of increasinglycomplex information processing speed continues to increase, and thus the radar controlsystem is also put forward higher requirements. Old radar system highly customizable,closed late lead to low maintenance, upgrades, and a series of difficult problems. FPGAas modern microelectronic technology development mainly reflected one has beenincreasingly used in radar electronic system design. Using FPGA can be radar controlsystem in accordance with an open system architecture design, the system can be usedmany times and debug system is small, simple structure, short design cycle.Programmable nature of FPGA-line, but also to the design of radar electronic systemhas good compatibility and scalability, ease of maintenance and expansion of otheradvantages.Therefore, the radar control system using FPGA design to become thedevelopment trend of modern radar systems.Thesis work is as follows:1, the use of software systems engineering design ideas, FPGA-based radarsynchronous control system design. Using FPGA design system, in accordance with thehierarchical, structured design methods, top-down from the system level to thefunctional module level hardware and software co-design, so as to achieve the seamlessintegration of software and hardware platforms and system control flexibility.2, the application of FPGA embedded system as a systems engineering design ofkey technologies, design system software and hardware platform. Achievesynchronization control radar system functions,modular design to FPGA programmingas the core, to achieve the synchronization control system clock divider, digital signalprocessing, data storage and forwarding system functions.3, the design of human-machine interface control platform, real-timesynchronization control system designed to control and testing to ensure systemreliability and stability, ease of ongoing maintenance and development.Paper designed to achieve synchronization control radar system performance tomeet the requirements, the system is operating normally, perfectly matched with theexternal other subsystems, to meet the indicators meet the design requirements.
