Design And Development Of Automatic Test System Based On Radar Simulator ADC/DAC Performance

Radar is irreplaceable important role whether in the military or in everyday life and in modern electronic detection equipment it is an important component. So radar testing has become a top priority, we emerged a number of radar simulator, including the target modeling, simulation and other kinds of radar echo simulator. The A/D converter and D/A converter is part of an important component, but its detection parameters become more and more complicated, in order to change this situation, the automated test platform can accurately and quickly complete detection of ADC/DAC module.First, this article analyzes the current testing techniques about some ADC/DAC modules and combined in the laboratory practical use ADC / DAC module, and developed a test automation software design, detailed discussion of the practical applicability and reliability of the system.Secondly, I design how to test the ADC / DAC performance of the radar simulator baseband, especially the method for the dynamic parameters of ADC module, and finally apply FFT to test the dynamic parameters of the ADC.Then, the automated testing software apply VS2010 software platform, using C ++ object-oriented programming, modular programming ideas, to write the various functional modules of the software.Finally, I find out a way to improve and optimize the point the point of the software based on the analysis and comparison of test results.The automated testing software for radar simulator ADC / DAC module test parameters, by actual test results and continuous commissioning in actual use, has been unanimously praised by users.
