Leli khasi liqhathanisa i-radar ye-AESA vs i-radar ye-PESA futhi likhuluma ngomehluko phakathi kwe-radar ye-AESA ne-radar ye-PESA. I-AESA imele i-Active Electronically Scanned Array kuyilapho i-PESA imele i-Passive Electronically Scanned Array.
●I-PESA Radar
Irada ye-PESA isebenzisa umthombo ovamile we-RF okwabelwana ngawo lapho isiginali ilungiswa kusetshenziswa amamojula alawulwa ngedijithali.
Okulandelayo izici ze-radar ye-PESA.
• Njengoba kukhonjisiwe kumfanekiso-1, isebenzisa imojula yesidlulisi/umamukeli oyedwa.
• I-radar ye-PESA ikhiqiza amaza omsakazo akwazi ukuqondiswa ngezindlela ezahlukene.
• Lapha izici ze-antenna zixhunywe nesidlulisi/umamukeli esisodwa. Lapha i-PESA ihlukile ku-AESA lapho kusetshenziswa khona amamojula ahlukene okuthumela/okwamukela ku-elementi ngayinye ye-antenna. Konke lokhu kulawulwa yikhompyutha njengoba kushiwo ngezansi.
• Ngenxa yemvamisa eyodwa yokusetshenziswa, inethuba elikhulu lokuminyanisa ama-jammer e-RF yesitha.
• Inesilinganiso sokuskena esinensayo futhi ingakwazi ukulandelela okuhlosiwe okukodwa noma isingathe umsebenzi owodwa ngesikhathi.
●AESA Radar
Njengoba kushiwo, i-AESA isebenzisa i-antenna yohlu olulawulwa nge-elekthronikhi lapho usebe lwamagagasi omsakazo lungaqondiswa khona nge-elekthronikhi ukuze likhombe okufanayo ezindaweni ezihlukene ngaphandle kokunyakaza kothi. Ibhekwa njengenguqulo ethuthukisiwe ye-radar ye-PESA.
I-AESA isebenzisa amamojula amaningi angawodwana namancane e-transmit/receive (TRx).
Okulandelayo izici ze-radar ye-AESA.
• Njengoba kuboniswe emfanekisweni-2, isebenzisa amamojula amaningi adlulisayo/nomamukeli.
• Amamojula amaningi okuthi Dlulisa/Yamukela axhunywe nezici eziningi ze-antenna ezaziwa ngokuthi i-array antenna.
• Irada ye-AESA ikhiqiza imishayo eminingi kumaza omsakazo ahlukene ngesikhathi esisodwa.
• Ngenxa yamakhono okukhiqiza amafrikhwensi amaningi ebangeni elibanzi, inamathuba amancane okuthi iminyaniswe ama-jammer e-RF ayizitha.
• Inezilinganiso zokuskena okusheshayo futhi ingalandelela okuhlosiwe okuningi noma imisebenzi eminingi.
