Performance of the robust FSBB using the WCMP optimization with the PRV constraint. Microphone gain errors (−0.1,0.1) and phase errors (−π/18,π/18). The steering direction ϕ d =60°. Average of 100 Monte Carlo trials. a Array response of the FSBB with PRV constraint (β=20). b Array response of the FSBB without PRV constraint. c Side view of a. d Side view of b. e PRV of the FSBB with PRV constraint (β=20). f PRV of the FSBB without PRV constraint. g Side view of e. h Side view of f
