level shifter
解釋
電平位移器-
As ttd ( true time delay ) is utilized in optically controlled phased array at sub - array level to replace the phase shifter in general phased array radar system, and make time delay compensation at sub - array level, which can reduce aperture effect considerably and make the broadband and wide - angle scanning of phased array antennas come true
由於光控相控陣雷達在子陣級上引入實時延時線ttd （ truetimedelay ）取代常規相控陣雷達中的移相器進行子陣級的延時補償，大大減輕了孔徑效應，使相控陣雷達實現了寬帶寬角掃描。 -
