Eli phepha lithelekisa i-radar ye-AESA kunye ne-radar ye-PESA kwaye likhankanya umahluko phakathi kwe-radar ye-AESA kunye ne-radar ye-PESA. I-AESA imele i-Active Electronically Scanned Array ngelixa i-PESA imele i-Passive Electronically Scanned Array.
●Iradar yePESA
I-radar ye-PESA isebenzisa umthombo we-RF ohlanganyelweyo apho isignali iguqulwa khona kusetyenziswa iimodyuli ze-phase shifter ezilawulwa ngedijithali.
Nazi iimpawu zeradar yePESA.
• Njengoko kubonisiwe kumfanekiso-1, isebenzisa imodyuli enye yokudlulisela/yokwamkela.
• Iradar yePESA ivelisa umsebe wamaza erediyo anokuqhutywa ngekhompyutha kwiindlela ezahlukeneyo.
• Apha izinto ze-antenna zidityaniswa ne-transmitter/receiver enye. Apha i-PESA yahlukile kwi-AESA apho kusetyenziswa iimodyuli ezahlukeneyo zokudlulisa/zokwamkela kuzo zonke izinto ze-antenna. Zonke ezi zinto zilawulwa yikhompyutha njengoko kukhankanyiwe ngezantsi.
• Ngenxa yokusetyenziswa rhoqo, inamathuba aphezulu okuvalelwa zii-jammer ze-RF zotshaba.
• Inesantya esicothayo sokuskena kwaye inokulandelela ithagethi enye kuphela okanye iphathe umsebenzi omnye ngexesha.
●Iradar ye-AESA
Njengoko kutshiwo, i-AESA isebenzisa i-antenna elawulwa nge-elektroniki apho umqadi wamaza erediyo unokuqhutywa nge-elektroniki ukuze ubhekise kwicala elinye kwicala elahlukileyo ngaphandle kokuhamba kwe-antenna. Ithathwa njengenguqulelo ephucukileyo ye-PESA radar.
I-AESA isebenzisa iimodyuli ezininzi zokuthumela/ukwamkela (TRx) ezizimeleyo nezincinci.
Nazi iimpawu ze-radar ye-AESA.
• Njengoko kubonisiwe kumfanekiso-2, isebenzisa iimodyuli ezininzi zokudlulisela/zokwamkela.
• Iimodyuli ezininzi zeTransmit/Receive zidibene nezinto ezininzi ze-antenna ezaziwa ngokuba yi-array antenna.
• I-radar ye-AESA ivelisa imisebe emininzi kwiifrikhwensi ezahlukeneyo zerediyo ngaxeshanye.
• Ngenxa yamandla okwenza iifrikhwensi ezininzi kuluhlu olubanzi, ayinawo amathuba amaninzi okuvalelwa zii-jammer ze-RF zotshaba.
• Inesantya esikhawulezayo sokuskena kwaye inokulandelela iithagethi ezininzi okanye imisebenzi emininzi.
