Leli khasi liqhathanisa i-radar ye-AESA ne-radar ye-PESA futhi likhuluma ngomehluko phakathi kwe-radar ye-AESA ne-radar ye-PESA. I-AESA imele i-Active Electronically Scanned Array kanti i-PESA imele i-Passive Electronically Scanned Array.
●I-PESA Radar
I-radar ye-PESA isebenzisa umthombo we-RF ohlanganyelwe ovamile lapho isignali iguqulwa khona kusetshenziswa amamojula we-phase shifter alawulwa ngedijithali.
Okulandelayo yizici ze-radar ye-PESA.
• Njengoba kuboniswe esithombeni-1, isebenzisa imodyuli eyodwa yokudlulisela/yokwamukela.
• I-radar ye-PESA ikhiqiza umsebe wamagagasi omsakazo angaqondiswa ngogesi ngezindlela ezahlukene.
• Lapha izakhi ze-antenna zixhunyaniswa ne-transmitter/receiver eyodwa. Lapha i-PESA ihlukile ku-AESA lapho kusetshenziswa khona amamojula ahlukene okudlulisa/okwamukelayo kuzo zonke izakhi ze-antenna. Zonke lezi zilawulwa yikhompyutha njengoba kushiwo ngezansi.
• Ngenxa yokusetshenziswa okuvamise ukusetshenziswa kanye, kungenzeka kakhulu ukuthi ivinjwe yizitha ezisebenzisa ama-RF.
• Inesilinganiso sokuskena esihamba kancane futhi ingalandelela ithagethi eyodwa kuphela noma iphathe umsebenzi owodwa ngesikhathi.
●I-AESA Radar
Njengoba kushiwo, i-AESA isebenzisa i-antenna ye-array elawulwa ngogesi lapho imisebe yamagagasi omsakazo ingaqondiswa khona ngogesi ukuze ikhombe okufanayo ngezindlela ezahlukene ngaphandle kokunyakaza kwe-antenna. Ibhekwa njengenguqulo ethuthukisiwe ye-radar ye-PESA.
I-AESA isebenzisa amamojula amaningi okudlulisa/ukwamukela (TRx) ngamanye kanye nalawo amancane.
Okulandelayo yizici ze-radar ye-AESA.
• Njengoba kuboniswe esithombeni-2, isebenzisa amamojula amaningi okudlulisela/okwamukela.
• Amamojula amaningi okudlulisa/ukwamukela axhumene nezinto eziningi ze-antenna ezaziwa ngokuthi i-array antenna.
• I-radar ye-AESA ikhiqiza imisebe eminingi kumaza omsakazo ahlukene ngesikhathi esisodwa.
• Ngenxa yamakhono okwenza imvamisa eminingi ebangeni elibanzi, ayinawo amathuba amaningi okuthi ivinjwe yizitha ezisebenzisa ama-RF jammer.
• Inezinga lokuskena elisheshayo futhi ingalandelela ama-target amaningi noma imisebenzi eminingi.
