%X <p>The present direction of arrival (DOA) estimation methods in impulsive noise are mostly based on the fractional lower order statistics, and the computational load is much heavier than the traditional methods based on the second-order moment. Utilizing the property of the impulsive noise, a new DOA estimation method is proposed. Firstly, the reference amplitude of the array receiving data is estimated, which is not influenced by the impulsive noise. Then, the data with amplitude higher than the reference amplitude is normalized. Finally, the common second-order moment method is exploited to estimate the DOAs. Theoretical analysis and simulation results show that the proposed method has small computational load, and is effective in the presence of strong impulsive noise.</p>
