Radar yeAESA vs PESAKuenzanisa kwemagadzirirwo maviri emagetsi akaskenwa. Ose ari maviri anofambisa radar beam nekudzora phase kuburikidza neantena elements dzakawanda, pasina kutenderedza antenna nemakanika kune shanduko yega yega inonongedza. Musiyano mukuru ndewekuti simba reRF rinogadzirwa uye rinodzorwa: passive electronically scanned array (PESA) inowanzo shandisa nzira yekutumira/kugamuchira pakati, nepo active electronically scanned array (AESA) ichiparadzira mamodules akawanda ekutumira/kugamuchira muaperture.
Ndeupi Musiyano Uripo Pakati peAESA nePESA Radar?
Musiyano uripo pakati peAESA nePESA radar inonyanya kukosha pakugadzirwa kweRF iri shure kwearray. Tafura iri pazasi inoratidza kutengeserana kweinjiniya kunowanzo fungwa panguva yekugadzira uye kuongorora system yeradar.
| Kuenzanisa | Radha yePESA | Radar yeAESA |
|---|---|---|
| Magadzirirwo eRF | Sosi yeRF ine simba guru inogoverwa kuburikidza ne network yekudyisa uye phase shifters | Mamodule mazhinji ekutumira/kugamuchira akaparadzirwa akabatana neantena elements kana subarrays |
| Kutungamira kwedanda | Kudzora kwechikamu chemagetsi pamusoro pevhu | Kudzora kwemagetsi uye amplitude ne high waveform agility |
| Kugona kwemabasa akawanda | Zvinoenderana nehurongwa hwehurongwa uye murongi wezvirongwa | Yakakodzera zvikuru kupatsanurana nekukurumidza kwekutsvaga, track nezvimwe zvinhu |
| Kushivirira kukanganisa | Kukundikana kweCentral RF-chain kunogona kuva nemigumisiro yakakura padanho resystem | Kukundikana kwemodule imwe neimwe kunowanzo deredza mashandiro zvishoma nezvishoma pane kumisa array yakazara |
| Kuoma kunzwisisa | Kazhinji mamodule eRF anoshanda mashoma | Kutarisirwa kwekupisa kunoda kutarisirwa zvakanyanya, kuenzaniswa, kudzorwa uye kubatanidzwa |
Chii chinonzi PESA Radar?
A array yakaskenwa nemagetsi isingashandeinoshandisa dhizaini yekutumira/kugamuchira ine simba guru. Simba reRF rinofambiswa kuburikidza ne network yekudyisa kuenda kune akawanda ma element anopenya, ukuwo ma phase shifters anodzorwa nemagetsi achigadzirisa phase pa element yega yega kuti atungamirire danda. Array pachayo inonzi passive nekuti aperture haina complete active transmitter/receiver module pa element yega yega.
Hunhu Hukuru hwePESA
- Kuskena nemagetsi:danda rinogona kutungamirirwa nekukurumidza pasina kufambisa chimiro chose cheantenna.
- Kugadzirwa kweRF kwakapararira:chinotumira chakajairika chinopa mukana wekupinda kuburikidza nezvikamu zvekugovera uye zvikamu zvechikamu.
- Magadzirirwo akavakwa:Tekinoroji yePESA inoshandiswa mumasisitimu akawanda eradar ari pasi pevhu, emugungwa uye emundege.
- Kugona kunoenderana nesystem:Kukwanisa kuteedzera, kugona kwewaveform uye kumhanya kwekuskena zvinoenderana nekugadzirwa kweradar yese, kwete chete kana aperture yacho iri PESA.
Zvakanakira uye Zvisingakwanisike zvePESA
PESA inogona kupa electronic beam steering chaiyo ine mamodule mashoma anoshanda akapararira kupfuura AESA. Izvi zvinogona kuderedza kuoma kweRF hardware. Zvisinei, kurasikirwa kwefeed-network uye kuvimba ne central transmitter zvinogona kukanganisa kushanda zvakanaka uye kushivirira kukanganisa. PESA haifanirwe kutsanangurwa otomatiki se single-frequency kana kuganhurirwa kune chinangwa chimwe chete; hunhu ihwohwo hunosiyana zvichienderana nekushandiswa kweradar.
Chii chinonzi AESA Radar?
An array inoshanda yakaskenwa nemagetsiine mamodule akawanda e solid-state transmit/receive akapararira mu antenna aperture. Module inowanzo dzora antenna element imwe chete kana subarray diki. Kudzora kwedhijitari kunobatanidza maitiro echikamu, amplitude, nguva uye waveform kuitira kuti radar ikwanise kutungamira uye kuronga nguva yemwaranzi neagility yakakwira.
Hunhu Hukuru hweAESA
- Mamodule eRF akaparadzirwa:Kugadzira magetsi nekugamuchira zvinoparadzirwa muburi rese.
- Kudzora danda remagetsi rinoshanduka-shanduka:Nzvimbo yedanda uye mafungu zvinogona kuchinjwa nekukurumidza kutsigira mabasa ekutsvaga, kutevera, kugadzira mapu uye kutaurirana uko sisitimu yakagadzirirwa ivo.
- Kudzikisirwa kwakanaka:Kukundikana kwemamodule ega ega kunowanzo kukonzera kudzikira zvishoma nezvishoma mukushanda panzvimbo pekurasikirwa zvachose kwearray.
- Kuenzanisa uye zvinodiwa pakupisa:Kufananidza mamodule, kubvisa kupisa, kugoverwa kwesimba uye software yekudzora zvinhu zvakakosha pakubatanidzwa kweAESA.
Zvakanakira uye Zvisingakwanisike zveAESA
Magadzirirwo eAESA anogona kupa kuvimbika kwakanyanya, kudzora mafungu anochinjika, kuronga mabasa nekukurumidza uye kugona kwakasimba kwekugadzirisa mafungu emagetsi. Mabhenefiti aya anouya nehuwandu hwakawanda hwemidziyo, kuedza kugadzirisa, zvinodiwa pakutonhodza uye mutengo. Kushanda chaiko kunoenderana nehukuru hweaperture, mafrequency ekushanda, simba rekubuda kwemodule, nhamba yeruzha, bandwidth, nzvimbo yezvikamu, angle yekuskena uye kugadzirisa masaini.
Ndeipi iri nani: AESA kana PESA?
Hapana mhinduro yakajairika. AESA inowanzo shandiswa kana mashandiro akawanda, kushivirira kukanganisa uye kugona kwekuchinja mafungu zvichikosha. PESA inogona kuramba ichishanda kana basa rinodiwa richigona kuzadzikiswa neRF chain yakabatana uye active-module architecture iri nyore. Mainjiniya anofanira kuenzanisa zvinodiwa zvesystem inoyerwa pane kusarudza nechidimbu chete.
Mamiriro ekupararira kwemvura anokoshawo. Nzira dzakawanda, kuvharika kwemvura uye kufamba kwemvura zvinogona kuchinja nhanho yakagamuchirwa uye kudzokororwa kwekuyerwa kwayo, saka ongororo dzeradar dzinofanira kutariswa.kupera kwenzira isina wayapamwe chete nehurongwa hwe array.
- Tsanangura mashandisirwo ekushanda uye bandwidth instantly.
- Gadza zvinodiwa zvekuskena, kuwedzera, divi rekuvhara, uye polarization.
- Sarudza zvinodiwa panguva yekutsvaga, kutevedza, uye nguva yemabasa akawanda.
- Ongorora simba rekutumira, kunzwisiswa kwemugamuchiri uye huwandu hwesimba.
- Ongorora zvirambidzo zvekupisa, zvemagetsi, zvemakanika uye zvezvakatipoteredza.
- Kugadzirisa hurongwa, kusimbisa uye nzira dzekuyera antenna.
Array Antennas uye RF Test Support kubva kuRF MISO
RF MISO ikambani inogadzira uye inopa antenna dzeRF ne microwave inotsigira tsvakurudzo yeantenna, kuyerwa uye kubatanidzwa kwesystem. Hatisi kuratidza radar yakazara seantenna imwe chete. Pane kudaro, mainjiniya vanogona kuongorora zvikamu zvakakodzera uye kuyedza mhinduro zvichienderana nebhendi refrequency rinodiwa, gain, polarization, interface uye mechanical envelope.
Ongorora RF MISOzvigadzirwa zve antenna dze array, antenna dzakarongwa, mapoinzi ekufambisa mafunguuyekugona kwekuyedza antennaKuti muongorore purojekiti, ipai bhendi rekushanda, polarization, gain target, beamwidth, zvinodiwa pakutsvaga, connector kana waveguide interface, zvirambidzo zvekuisa uye mamiriro ekunze.
Mibvunzo Inowanzo bvunzwa
Ko AESA nePESA vanogona here kudzora mwenje nemagetsi?
Ehe. Magadzirirwo ese ari maviri anoshandisa hukama hwezvikamu zvakadzorwa pakati pezvinhu zve array kuti atungamirire danda pasina kutenderedza gomba rakazara nehunyanzvi hwese hwekutarisa.
Ko AESA inogara iri nani pane PESA here?
Kwete. AESA ine zvakanakira zvakakosha mukufamba kwenguva, kudzokororwa kwesimba uye mashandiro akawanda, asi zvakare inounza hardware inoshanda zvakanyanya, manejimendi yekupisa uye kuoma kwekugadzirisa. Sarudzo chaiyo inoenderana nebasa uye zvinodiwa nesystem.
Sei AESA ichigona kuramba ichishanda mushure mekukundikana kwemodule?
Nekuti kugadzirwa kweRF uye kugamuchira zvinogoverwa mumamodule mazhinji. Kukundikana kwemamodule kushoma kunowanzo deredza mashandiro e aperture aripo zvishoma nezvishoma, kunyangwe mhedzisiro chaiyo ichienderana nekugadzirwa kwearray nenzvimbo yekukanganisa.
Ndezvipi zvikamu zve antenna zvinokosha pakuongorora radar array?
Zvikamu zvakakosha zvinosanganisira mashandiro ekushanda, bandwidth, polarization, gain, beamwidth, sidelobe level, cross-polarization, element spacing, scan loss, impedance match, power handling uye electrical and mechanical interface.
Kurukurai Zvinodiwa NeRF Antenna Yenyu
Bata RF MISO kuti uwane ruzivo rwema frequency auri kushandisa uye zvinodiwa zvehunyanzvi kuti uwane rutsigiro rwekusarudza chigadzirwa.
