Abstract: Aiming at the problem of amplitude phase inconsistency and coupling of millimeter wave radar ar-ray antenna, the coupling and amplitude phase inconsistency between antennas are modeled, and a compensa-tion and correction method based on least square method is proposed to realize the correction and compensa-tion of antenna array, and improve the angle measurement accuracy of space target by the antenna array of millimeter wave radar. Simulation and experimental data show that the proposed method can significantly improve the angle measurement accuracy of millimeter wave radar.
