  • Abstract
    This paper presents a phase unwrapping algorithm based on the extended kalman filter (EKF) for multi-baseline SAR interferometry. This algorithm achieves simultaneously noise filtering and phase unwrapping by combining an EKF with a conventional path-tracing strategy. The simulation data processing results validate the effectiveness of proposed method, and show a significant improvement with respect to some conventional algorithms in some situations.
