CALIBRATION APPARATUS OF ARRAY ANTENNA IN RADAR SYSTEM USING COUPLING LINE AND METHOD THEREOF

摘要

The present invention relates to an array antenna compensation apparatus in a radar system and a method thereof capable of accurately compensating power level and phase of the array antenna in the radar system. The array antenna compensation apparatus in the radar system according to an embodiment of the present invention comprises the steps of outputting a signal via a coupling line of the array antenna and compensating the array antenna as a result of a difference value between the signal and initial compensation data.
