In this paper, we consider the problem of estimating the two-dimensional (2-D) harmonic frequencies in presence of noise and outliers. We propose a subspace method based robust estimation procedure to estimate the unknown frequencies. The proposed method is based on the efficient PUMA method and robust M-estimation techniques. The method is efficient with respect to presence of outliers in the data. The simulation experiments verify the feasibility and effectiveness of the proposed method.
