Parameter Estimation of Target in Interference Localization Background in Impulse Noise Environment

摘要

This paper proposes an airplane parameter estimation algorithm based on the study of the problem of interference localization in impulsive noise environment. Firstly, an extended signal model to accurately estimate parameters of the target is proposed with Alpha-stable distribution model. A method of Doppler estimation based on the peak of the fractional lower-order power spectrum is proposed. The 2D-FLOS-MUSIC algorithm is applied to estimate the azimuth angle and elevation angle. The correctness and effectiveness of the proposed method are verified with the computer simulation.
