In this section, we examine the robustness performance of the
developed system using the robust Huber beamformer proposed
in [20]. We use the same experimental data as those used in
the previous section. A computer-generated impulsive noise is
used. Observations used for robustness measure are obtained by
adding this impulsive noise to the experimental data, as shown
in Fig. 10.
We use the mixed-noise model consisting of the Gaussian
and Cauchy distribution components with the following probability
density function
