Title:
アレイ通信装置、及びその制御方法
Document Type and Number:
Japanese Patent JP7417520
Kind Code:
B2
Abstract:
Provided are an array communication device that makes phase correction between a plurality of arrays having bi-directional amplifiers possible and a method for controlling the array communication device. This array communication device comprises a plurality of array units that are connected to a common signal processing unit and each comprise an antenna, amplifier, and phase shifter. The array communication device further comprises first-directional couplers that are respectively disposed between the antennas and amplifiers of the array units and divide or combine signals, second-directional couplers that are respectively disposed between the phase shifters of the array units and the signal processing unit and divide or combine signals, and phase comparison means that each receive at least one from among a signal from a first-directional coupler and a signal from a second-directional coupler and a signal serving as a phase reference and carry out phase comparison and correction.
