Qhov kev hloov pauv ntawm Passive Electronically Scanned Array (PESA) mus rau Active Electronically Scanned Array (AESA) sawv cev rau qhov kev nce qib tseem ceeb tshaj plaws hauv cov thev naus laus zis radar niaj hnub no. Txawm hais tias ob lub tshuab siv lub zog hluav taws xob, lawv cov qauv tseem ceeb sib txawv heev, ua rau muaj kev sib txawv ntawm kev ua tau zoo.
Hauv PESA systems, ib lub transmitter/receiver unit pub rau lub network ntawm cov theem shifters uas tswj cov qauv hluav taws xob ntawm cov khoom passive antenna. Qhov kev tsim no tsim cov kev txwv hauv kev tiv thaiv jamming thiab beam agility. Qhov sib piv, AESA radar suav nrog ntau pua lossis ntau txhiab tus kheej transmit/receive modules, txhua tus nrog nws tus kheej theem thiab amplitude tswj. Qhov kev faib tawm architecture no ua rau muaj peev xwm hloov pauv suav nrog kev taug qab ntau lub hom phiaj tib lub sijhawm, adaptive beamforming, thiab txhim kho cov khoom siv hluav taws xob tiv thaiv.
Cov ntsiab lus ntawm lub antenna lawv tus kheej tau hloov zuj zus nrog rau cov kab ke no.Cov kav hlau txais xov planar, nrog lawv cov qauv tsim qis, tsim tau ntau, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau AESA systems uas xav tau compact, conformal installations. Lub caij no, ODM conical horn antennas txuas ntxiv ua lub luag haujlwm tseem ceeb hauv cov ntawv thov tshwj xeeb qhov twg lawv cov qauv symmetrical thiab dav
Cov txheej txheem AESA niaj hnub no feem ntau muab ob qho thev naus laus zis sib xyaw ua ke, kev sib xyaw ua ke ntawm cov planar arrays rau cov haujlwm tseem ceeb scanning nrog conical horn pub rau kev pabcuam tshwj xeeb. Txoj hauv kev sib xyaw no qhia tau hais tias kev tsim cov kav hlau txais xov microwave tau dhau los ua qhov nyuaj dua los ua kom tau raws li ntau yam kev xav tau ua haujlwm thoob plaws hauv kev ua tub rog, kev tsav dav hlau, thiab kev siv huab cua.
