ANT051 Afar Element Spiral Antenna Array
| Hogaamiye-mw | Hordhac Afar Element Spiral Antenna Array |
Soo bandhigida tignoolajiyada microwave-ka ee hogaamiyahaArray-gacan-goyntan waxaa loogu talagalay in lagu beddelo habka aan u aragno oo aan u isticmaalno nidaamyada anteenada, taasoo keenaysa waxqabad aan la mid ahayn iyo kala-duwanaanshaha naqshad kooban oo hufan.
Wadnaha shaxdan kacaanku waa curiyaha anteenada helicalka, kaas oo si taxadar leh loogu dhex daray qaab dhismeedka madal duuban.Dhismuhu wuxuu ka kooban yahay dusha sare iyo dhinacyo badan, mid kasta oo ka mid ah wuxuu ku xiran yahay cidhifka dusha sare.Dhinacyada dhinacyada ku xiga ayaa sidoo kale isku xiran, iyaga oo abuuraya madal aan fiicneyn oo xooggan oo loogu talagalay walxaha anteenada.
Naqshadaynta gaarka ah ee qaab dhismeedka madal la duubay ayaa u oggolaanaysa walxaha anteenada helical in la dhigo xagga sare iyo dhinacyada, kor u qaadista daboolida iyo waxqabadka.Qaabayntan ayaa awood u siinaysa in ay soo diyaariyaan alwaaxyo badan oo qaab stereoscopic ah, taas oo kor u qaadaysa soo dhawaynta iyo gudbinta nidaamka anteenada.
Mid ka mid ah astaamaha muhiimka ah ee qaab dhismeedka madal duuban ayaa ah qaabka caadiga ah ee geeslaha ah ee dusha sare, kaas oo sii wanaajinaya qaybinta isku midka ah ee walxaha anteenada waxayna wanaajisaa waxqabadka guud ee isku dubaridka.Tani waxay hubinaysaa in isku dubaridu ay keeni karto awood calaamadeed oo joogto ah oo la isku halayn karo oo dhan codsiyo iyo deegaan kala duwan.
