ARRAY ANTENNA RECEIVING DEVICE AND METHOD FOR CALIBRATING RECEIVED SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide an array antenna receiving device which can calibrate a received signal in high accuracy without generating an unnecessary radiation in an antenna unit and even when a power level of the received signal is low.

SOLUTION: The array antenna receiving device generates a reference signal by the operation of a reference signal generator 123 only when the power level of the received signal captured by the antenna unit 111 is low. An error calculator 122 calculates the error of the received signal generated at the received signal by signal processing in a receiving unit 110 by comparing information S3 of the received signal superposed with the reference signal with a calibrating signal S4, and orders the compensation of the received signal to a received signal processing unit 121 based on the error of the calculated received signal.
