Abstract

PURPOSE:To give interchangeability for a variable phase shifter, by providing an operator adding or subtracting a correction signal specific to the phase shifter and a digital phase shift signal fed from a beam scanning control circuit with a variable phase shifter and arranging the relative phase between the variable phase shifters. CONSTITUTION:Microwave power produced from a microwave generator is fed to a distributor via a feeding line and fed to a radiation element via a variable phase shifter after being distributed in a plurality. A digital phase shifter 82 of a variable phase shifter 81 is driven with a driving circuit 83. Further, to correct the dispersion of phase between elements in forming the in-phase surface except the specific phase of microwave transmission line from said power feeding line to the radiation end of radiation elements, the digital phase signal phi fed from a beam scanning control circuit and the corrected phase angle signal DELTA specific to a digital phase shifter 82 are added or subtracted at an operation circuit 85, feeding the result to the driving circuit 83 with a beam direction instructing signal.
