For the problem of coherent and uncorrelated signals direction finding under impulsive noise, an efficient method is designed. Firstly, a threshold value was established according to a novel adaptive algorithm. Secondly, all the amplitude in the received data that is higher than the threshold value, was replaced by the threshold value. Finally, the classical methods based on second-order statistics are employed to estimate the Direction Of Arrival. Theoretical analysis and simulation results show that the proposed method is effective in environments of strong impulsive noise, and it has better performance than the methods based on fractional lower order statistics.
