EHF(Extremely High Frequency)是指在30GHz至300GHz的頻率范圍內(nèi)的電磁波,是一種超高頻率的電磁波,也稱為極高頻率(EHF)。
EHF的應(yīng)用非常廣泛,它可以用于通信,測量,監(jiān)測,遙控,導(dǎo)航,遙感,探測,定位,檢測,測距,定位,探測,搜索,控制,識別,跟蹤,攔截,攔截,監(jiān)視,監(jiān)控,探測,探測,測量,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測,檢測
