ANTENNA DEVICE, ACTIVE PHASE ARRAY RADAR PROVIDING SAME, AND ERROR CORRECTION METHOD THEREOF

摘要

The present invention provides an antenna device, which comprises: a plurality of antennas disposed at a predetermined location; a plurality of transmission/reception modules connected with each antenna so as to emit a transmission signal or receive a reception signal through the antenna in accordance with an input set value; a calculation module capable of calculating an error ratio between the transmission/reception modules using a mutual coupling value between the antennas and a transfer function value between the transmission/reception modules; and a correction module connected with the calculation module and capable of controlling the operation of each transmission/reception module in accordance with the calculated error ratio. An error can be corrected by using an interconnection phenomenon occurring between the antennas.;COPYRIGHT KIPO 2020
