Fig. 5From: Robust design of Farrow-structure-based steerable broadband beamformers with sparse tap weights via convex optimizationArray response of the robust FSBB using the less-conservative WCP optimization in the presence of microphone mismatches, with the user-defined parameter ε being reduced from 1.74 to 0.02. The steering direction ϕ d =60°. Average of 100 Monte Carlo trials. a 3D view of the array response. b Side view of the array responseBack to article page
