Phased-array radar has a huge array of microwave feeding network and antenna lobe performance depends on the array amplitude and phase errors. Therefore, it is necessary to monitor the array surface to ensure the performance of the array. In the traditional test method, there is a bad test precision and slow speed. In this paper, a monitoring method based on compensation correction technique is proposed. The inside and outside of the measurement method, two kinds of tests complement each other,
