Development Of Portable Radar Testing Equipment Based On ZYNQ

As the core part of weapon system,the performance of the radar equipment directly determines its precision and reliability.Therefore,the development and progress of radar technology are of great significance to the enhancement of the national defense force.In the whole life cycle of radar equipment,from product development to final use and maintenance,and with continuous upgrading,radar testing facilities are needed to all-roundly monitor and test various performance of radar,which are developing towards miniaturized,universal and modular real-time testing direction.This thesis firstly analyzes the demands of miniaturization and real-time for radar testing equipment,then the overall scheme of a portable radar testing equipment based on ZYNQ is determined.The hardware is modularizly composed of core control module,serial communication module and function interfa ce module.The core controller adopts ZYNQ-7000 series chip,and serial interfaces that communicate with radar equipment,INS and GPS are implemented on board.It also includes SD card interface,Ethernet port,USB interface,debug serial port,HDMI interface and other functional interfaces.In the software design,the firmware logic mainly completes the serial communication control logic,the PS-PL communication logic and the video output logic in ZYNQ PL.In the embedded software development,embedded Linux system and application software program are transplanted and designed respectively in ZYNQ PS,which can realize independent testing work out of industrial control machine.The application software development adopts multi-thread technology and real-time thread scheduling strategy,which ensures the real-time performance of communication and processing with radar.In addition,in order to improve the real-time efficiency of data storage,this thesis optimizes the Linux file system in depth.As a result,The entire radar testing equipment can meet the requirements of portability,real-time,versatility and scalability.The results of experimental verification and outfield joint debugging show that,this portable radar testing equipment has been tested and verified from hardware performance to system function.It can achieve real-time communication and processing function with radar equipment,realizing the data transmission,calculation,storage and state parameter display in 5ms/10 ms cycle.It can realize function of telemetry communication and imaging with radar equipment,sending timing pulses in the period of 10 ms and receiving the returned telemetry data to depict telemetry images.This radar testing equipment works independently with stablity and reliablity in the testing process,thus can complete actual testing task.
