<p>PURPOSE:To simplify a circuit and to improve serviceability, by transferring information on the amount of phase shifting, amplitude, etc., through an optical fiber cable and performing a serial connection to a phase shifting element. CONSTITUTION:A radar processor 3 sends a radar mode signal and an angle command signal to a beam steering processor 7. This processor 7 calculates phase information at a high speed in order to generates a radio wave beam in the sent angle direction and sends the information to a phased array antenna part 6. The amplitude data is sent to the antenna part 6 only when radar modes are changed. The optical fiber cable is used as a medium for transmitting the control information between the processor 7 and antenna part 6.</p> |
