Robust DOA Estimation via Sparse Signal Reconstruction With Impulsive Noise

Abstract

In this letter, direction of arrival (DOA) estimation is considered for an impulsive noise case. The original complex-valued measurement for DOA problem is expressed as an augmented real-valued measurement using the real and imaginary parts. To deal with the impulsive noises, a function approximation technique is used. For the real-valued model, a robust DOA estimation algorithm is proposed based on sparse signal reconstruction. Simulation is given to demonstrate the validity and superiority of our method.
