Abstract	This paper presents a signal processing method for calibrating an antenna array to solve the inaccuracy of Direction of Arrival(DOA). Using reference data quantifying amplitude and phase distortion levels for each angles, we compensate each radar array’s amplitude and phase distortion. The proposed method is applied to the Bartlett, Capon and MUSIC algorithms, Using 77 GHz Frequency Modulated Continuous Wave(FMCW) Long Range Radar(LRR) signal, we experimentally demonstrate the performance improvement after the proposed compensation.
