Uru rupapuro rugereranya radar ya AESA na radar ya PESA kandi ruvuga itandukaniro riri hagati ya radar ya AESA na radar ya PESA. AESA isobanura Active Electronically Scanned Array mu gihe PESA isobanura Passive Electronically Scanned Array.
●Radar ya PESA
Radar ya PESA ikoresha isoko rusange rya RF aho ikimenyetso gihindurwa hakoreshejwe modules za phase shifter zigenzurwa mu buryo bw'ikoranabuhanga.
Ibi bikurikira ni ibiranga radar ya PESA.
• Nkuko bigaragara ku ishusho ya 1, ikoresha module imwe yo kohereza ubutumwa/kwakira ubutumwa.
• Radar ya PESA ikora imirasire y'amaradiyo ishobora kuyoborwa mu buryo bw'ikoranabuhanga mu byerekezo bitandukanye.
• Aha ibintu bya antene bihuzwa na transmitter/receiver imwe. Aha PESA itandukanye na AESA aho modules zitandukanye zo kohereza/kwakira zikoreshwa kuri buri kimwe mu bintu bya antene. Ibi byose bigenzurwa na mudasobwa nkuko byavuzwe haruguru.
• Bitewe n'ikoreshwa rimwe gusa, hari amahirwe menshi yo kugongwa n'abanzi ba RF.
• Ifite umuvuduko muto wo gushakisha kandi ishobora gukurikirana intego imwe gusa cyangwa gukora akazi kamwe icyarimwe.
●Radar ya AESA
Nkuko byavuzwe, AESA ikoresha antene igenzurwa n'ikoranabuhanga aho imirasire y'amaradiyo ishobora kuyoborwa mu buryo bw'ikoranabuhanga kugira ngo yerekeze kimwe mu byerekezo bitandukanye nta kuntu antene igenda. Ifatwa nk'uburyo bugezweho bwa radar ya PESA.
AESA ikoresha module nyinshi zo kohereza no kwakira amakuru ku giti cyazo (TRx) n'iziciriritse.
Ibi bikurikira ni ibiranga radar ya AESA.
• Nkuko bigaragara ku ishusho ya 2, ikoresha module nyinshi zo kohereza ubutumwa/kwakira ubutumwa.
• Module nyinshi zo kohereza no kwakira zihuzwa n'ibintu byinshi bya antene bizwi nka antene y'uruhererekane.
• Radar ya AESA ikora imirasire myinshi ku maradiyo atandukanye icyarimwe.
• Bitewe n'ubushobozi bwo gukora frequency nyinshi mu buryo bwagutse, nta mahirwe menshi ifite yo kubuzwa n'abanzi ba RF.
• Ifite ubushobozi bwo gushakisha vuba kandi ishobora gukurikirana intego nyinshi cyangwa imirimo myinshi.
