Design And Implementation Of The Control Software For The Vehicle-mounted Synthetic Aperture Radar Host Computer

Synthetic Aperture Radar(SAR)is a radar imaging system that uses a signal processing technique to make a small aperture antenna equivalent to a large antenna to improve the resolution.It has the characteristics of high resolution,all-day and all-weather operation.In recent years,SAR has developed rapidly.Not only can it obtain high-quality imaging images,but also has the advantages of simple hardware equipment,low cost,easy operation and stable performance.Based on the Vehicle-Mounted synthetic aperture radar,the research on the control software is carried out.Firstly,the technical requirements of the radar system and the technical indicators are analyzed,and the system's workflow is introduced,and software development scheme are designed systematically.Secondly,the principle of system self-test and grazing angle estimation is simulated by Matlab.Thirdly,the object-oriented programming is used to complete the development of the control software that contains designing the software structure,the communication protocol and the driver to make the PCIe communication based on WinDriver.Fourthly,the Vehicle-Mounted synthetic aperture radar imaging system and the field experiment are completed.The control software of Vehicle-Mounted synthetic aperture radar in this paper is verified by radar test,which can meet the design target and has perfect performance.It can also extend the follow-up function in software design and have high practicality.
