Design Of Parameters And Control Software For Transceiver HFSWR

With the development of radar technology,radar system miniaturization,digitalization and software has gradually become the future development trend of radar.The miniaturization of the radar system is mainly to optimize the radar antenna array to solve the problems caused by the transceiver antenna.Digitalization of the radar system is the process of the system design using digital waveform generation,digital sampling,digital signal processing technology.Radar system software is the radar system control function using software programming way to manage the radar system to achieve flexible control.Transceiver high frequency surface wave radar system is used to send and receive shared antenna technology,the system hardware design using digital technology.Based on the system as the research object,on the parameters of the radar system and control software design.Radar system parameters design is mainly aimed at radar waveform parameters and working frequency design.Radar transmit signals take the ambiguity function as the breakthrough point,to study the application of various signal forms.The signal waveform parameters are designed for the given radar performance and target characteristics under conditions of no distance ambiguity and no speed ambiguity.The design of radar work frequency is based on the signal clutter noise ratio as the breakthrough point,and the external environment of the radar is modeled,by the minimum signal clutter noise ratio detection threshold launch the working frequency of radar,so that the radar detection range can be optimized.Radar system timing is the core of the radar system,the design of system timing need to be aware of the operation process of the system.By analyzing the radar system to run the start-up period,auxiliary period and the working state of the detection period of the hardware equipment,the radar system working timing diagram is designed according to the radar work requirements,which can provide reference for the design of the subsequent system control software.Based on the composition and function analysis of the radar analog frontend hardware,the overall scheme of the system control software design is determined.Based on the analysis of radar system function and timing process using Qt software is designed and completed a radar system control software,the control software adopts the modular design,can the independent testing equipment,also can establish the connection with central mainframe and the signal processor to run the whole.In order to verify the function of radar system control software,set up radar system control software debugging environment,and successfully verify the software control function.
