Real-Time Phased-Array Monitoring System for On-Site Calibration Using Beam-Steering Mode

In this paper, a novel real-time phased array monitoring method is proposed for the on-site phased-array calibration during the mission operation. The proposed method can successively estimate the individual element fields and its variations during the beam-steering, with the aid of the Kalman filter. Numerical simulations have demonstrated that the proposed method can effectively estimate the element fields along with the beam steering.
