Abstract:To met the high-reliability and real-time data transmisson requirements of the ARINC453 bus between the meteorologicaloperationaircraft misionsystemandtheairborne meteorologicalradar,adedicatedreceiverbasedonFPGAis designed.With Xilinx Spartan-3FPGA as the core,following the ARINC453 protocoland ARINC708electrical specifications, a modulardesign isadopted to implementthe full-process processngofmeteorological radardataacquisition,decoding, synchronousdetection,parsing,andverification,replacingtraditionaldedicatedchips tosolvetheproblemsofpooradaptability anddiffcultyincustomization.ThelogicdesigniscompletedbasedonVHDL,andhardwareverificationshows thatthereceiver worksstablyat astandardclockof 1MHz ,withaframe synchronizationaccuracyrateof 100% . Itcan accuratelyreceive meteorologicalradarechoes,detectionparameters,andotherdata,adapttothecustomizationrequirementsofadarequipment interfaces,and meet thereliability requirements ofthe data transmission link in meteorological operation scenarios.
