Abstract:
The presence of impulsive noise can severely degrade the accuracy performance of conventional direction of arrival estimation algorithms. In this paper, we propose a non-linear transformation function to suppress the impulsive noise. The proposed function is called Modified Modulus Transformation and it is used to preprocess the impulsive noise contaminated signal prior to covariance estimation. Simulation results are presented to illustrate the efficacy of the proposed approach for high resolution direction finding in highly-impulsive environments. This observation is also corroborated with real data.
