Maxay yihiin sifooyinka ugu muhiimsan ee anteenooyinka DF?

Anteenada jihada raadinta(anteenada DF) waxaa inta badan loo isticmaalaa in lagu helo calaamadaha hirarka korantada. Waxay ka kooban tahay anteenooyin badan oo anteeno ah oo meel bannaan loo habeeyey iyadoo la raacayo qaab gaar ah. Marka loo eego hababka kala duwan ee raadinta jihada, canaasiirta anteenada waxaa loo habeeyey qaabab kala duwan si loo gaaro jihada raadinta. Waxqabadka nidaamka raadinta jihada wuxuu si dhow ula xiriiraa anteenada DF ee ku xiran, gaar ahaan jihada raadinta saxnaanta, dareenka iyo xasaanadda calaamadaha xooggan.

ZD-DFA-3060-NFDFanteenowaa aalad raadiyaha jihada raadiyaha ee waxqabadka sare leh looguna talagalay codsiyada u baahan cabbirka jihada saxda ah.

Halkan waxaa ah faahfaahin ku saabsan anteenada:

Tilmaamaha ugu muhiimsan

1. Daboolista inta jeer

300 MHz ilaa 6 GHz: Dabool ballaaran oo xadhkaha soo noqnoqda ee badan, oo ku habboon falanqaynta iyo goobta calaamadaha raadiyaha badan.

2. Madax banaan laakiin isku dhafan anteeno la socodka firfircoon

• Waxay siisaa dareen-sare oo daboolan jiho kasta.
• Naqshadeeyay isla dhidibka anteenada ugu weyn ee DF (Direction Finding) si loo hubiyo cabbirro sax ah oo joogto ah.
• Wax faragelin ah kuma keeni doono hawlgalka caadiga ah ee ciidanka DF-ka.

3. Awoodda cabbiraadda jihada

Awood u leh inuu si sax ah u go'aamiyo jihada gudbinta ee signalka raadiyaha ee la helay.

Macluumaadka jihada waxaa loo isticmaali karaa in lagu helo isha ishaarada, taas oo muhiim u ah jawaabta degdega ah, la socodka amniga iyo meelaha kale.

4. Xaalado kala duwan oo codsi ah

• Caawinta hagidda: Waxay caawisaa in la go'aamiyo meesha walxaha dhaqaaqa.
• Hawlgallada goobidda iyo samatabbixinta: Si dhakhso leh u hel goobta dadka dhibaataysan.
• Aqoonsiga isha faragelinta: Soo hel isha faragelinta korantada.
• Ururinta sirdoonka isha: Falanqee oo daba gal calaamadaha gaarka ah.

5. La jaanqaadi kara tripod

Naqshadeynta ku-qaadista iyo dabacsanaanta, waxaa loo isticmaali karaa saddex-geesoodka caadiga ah si sahlan loo geeyo deegaanno kala duwan.

6. Waxqabadka la hagaajiyay

Anteenada kanaal kasta waxaa loo hagaajiyay inta jeer ee ay gaar u tahay.

Saxnimada sare ee azimuth ayaa la gaaraa, iyadoo la hubinayo isku halaynta natiijooyinka cabbirka.

7. Faa'iidooyinka codsiga

• Saxnaanta sare: Thanks to design horumarsan iyo algorithms-hagaajinta, waxay bixin kartaa xallinta jiho heer sare ah.
• Fududeynta isticmaalka: Qaab dhismeedka isafgaradka ah iyo is-dhex galka saaxiibtinimo ayaa ka dhigaya aaladda mid sahlan oo degdeg ah in la dejiyo lana isticmaalo.
• Dabacsanaan: Waxaa loo isticmaali karaa labadaba si go'an iyo mobile, iyadoo la qabsanaysa xaaladaha kala duwan ee goobta iyo shuruudaha hawlgalka.
