一种小型弹载瞬时测频接收机的研究与实现

摘要

为实现小体积下的瞬时测频，采用射频宽开+特殊编码体制来实现瞬时测频的接收机。介绍了该接收机的原理组成及其实测指标，总结其优点。该接收机具有瞬时带宽大、灵敏度高、动态范围大、测频时间短、体积小、质量轻、成本低、可靠性高等特点，适合弹载等多种恶劣环境的应用。%　　Theinstantaneousfrequencymeasurementreceiverintheproposedsystemisrealizedbasedon wideradiofrequencybandandspecialcodingrude,whichcanachieveinstantaneousfrequencymeasurementu-singsmallvolumedevice.Thedesignprinciple,practicalmeasuredspecificationandconstitutionofthereceiver areproposed.Thereceivercanadapttolotsofharshenvironmentsuchasmissile-borneenvironmentforits largeinstantaneousbandwidth,highdynamicrange,shortfrequencymeasurementtime,smallvolume,light weight,lowcostandhighdependability.
