MIMO雷达波形设计及参数估计研究的开题报告

【选题背景】

Withthedevelopmentofradartechnology,MIMO(multiple-inputmultiple-output)radarbecomesmoreandmorepopularbecauseithassignificantadvantagesovertraditionalsingle-antennaradarintermsofresolution,detection,andanti-interferenceability.IntheMIMOradarsystem,multipleantennasareusedatboththetransmittingandreceivingend,whichenablesthesystemtoformmultiplebeamsindifferentdirectionsandutilizespatialdiversity.OneimportantaspectoftheMIMOradarsystemiswaveformdesign,whichplaysacriticalroleinimprovingthesystemperformance.Thewaveformdesignaimstooptimizethetransmitsignalsothatthesystemcanachieveimproveddetection,localization,andclassificationperformance.Atthesametime,accurateestimationofMIMOradarparameters,suchastimedelayanddirectionofarrival,isfundamentaltothesuccessfuloperationofthesystem.
