Abstract

PURPOSE:To reduce the memory capacity of the phase-shifting memory, by deriving the extent of the phase-shifting by means of adding the value of the phase-shifting extent memory and that of the phase-shifting correction extent memory, in the antenna beam control unit of an array antenna. CONSTITUTION:The phase-shifting extent memory 1a stores the extent of the phase-shifting of (i)X(k) pieces corresponding to the number (i) of phase shifters and the number (k) of beam directions, and when it is desired to direct an antenna beam to one specific direction, the phase-shifting extent is derived by reading out the phase-shifting extent phiik and the value DELTAphii of the phase-shifting correction extent memory 1b, and deriving phiik-DELTAphii or phiik+DELTAphii by the addition circuit 6. And this signal is sent to the driver control circuit 3 by executing the timing control for driving the driver 4 by the buffer register 2, and distribution of the extent of the phase-shifting to each phase shifter, the driver 4 is driven, and the antenna beam is directed in the specified direction by the phase shifter 5.
