4. Ukunciphisa i-aturation kunye nokudibanisa okuphezulu
Iteknoloji yothumelo lwe-microwave oluphambili kunye neenkqubo zokuvelisa i-semiconductor zidibanisa imigca yokulibaziseka yekhebula enkulu okanye i-coaxial ngokwesiko kwiphakheji encinci, zibonelela ngokulibaziseka okuzinzileyo, amandla aqinileyo okulwa nokuphazamiseka, kunye nokuhlanganiswa okulula kwenkqubo, ukoyisa ukusilela kwemigca yokulibaziseka yendabuko efana nobukhulu obukhulu, ilahleko ephezulu, kunye nokusasazeka okukhulu.

Izicelo:

1. I-radar ye-wideband phased array
Kwiinkqubo ze-radar ezisebenzisa i-wideband phased array, i-antenna beam pointing iyashukuma ngokusebenza rhoqo ngenxa yeziphumo ze-aperture.
