The Design Of Signals Source Based On A Certain Radar Data Recorder

Data gather recorder equipment is an equipment used to gather and recordradar signal. This is a design department consign this laboratory to develop.In order to measure data gather recorder equipment's correctness, the laboratorydesign a measure device to satisfy the design, produce and manufacture. Theequipment provided all of in-out signal to data gather recorder equipment. Itcan provide power, signal source, reading function and signal data's judgefunction, etc. Due to radar signal gather recorder equipment's particularity,the paper mostly introduced gather recorder equipment signal source's design.It introduced the current situation with domestic and international anddevelopment trend of signals source. Moreover introduced signals source fromsystem aspect scheme design, system hardware design, system software design andanti-jamming design. Discuss the characteristic and function of the system inthe round. The developed signal source system can achieve the signals outputsuch as control signals, analog signals, clock signals and so on, and achievethe function of power supply module.According to data gather and record's demand, the paper put forward thedesign's scheme of modularize. It made use of FPGA or CPLD as the system's centercontrol logic, which improved the systematic flexibility. It introduced thedesign of hardware in every function module as well as key technology realizedin detail。Its main function modules include: center control logic module, lowspeed signal fountain D/A conversion circuit module, low speed signal fountainsampling keep magnify circuit module, high speed signal fountain clock signaldifference output circuit module, high speed diver signal fountain differentialstrain wave magnify circuit module and power supply module.In addition, the paper combine anti-jamming question and put forward variouskinds of anti-jamming measurements to the system. It includes electrical sourcedesign, PCB board arrangement, center control logic design and the anti-jammingdesign of software, etc.
