Performance comparison of the sparse robust FSBB and its non-sparse counterpart. For the non-sparse FSBB, the number of active weights is 1500; while for the sparse FSBB, the number of active weights is 738, i.e., over half of tap weights have been nullified. The steering direction ϕ d =60°. Average of 100 Monte Carlo trials. a Array response of the sparse FSBB. b Array response of the non-sparse FSBB. c Side view of a. d Side view of b. e PRV of the sparse FSBB. f PRV of the non-sparse FSBB. g Side view of e. h Side view of f
