Dependence of dual state beamformer t-peak dimension on beamformer type. SNR = 1, a = 5 cm. a Peak dimension as a function of n int (n ext = 3), solid gray––conventional; solid black––SSS, noise covariance matrix diagonalized; dashed black––SSS, nondiagonal noise covariance matrix. b–f Intersection of beamformer peak with y–z plane, crosses indicate true source positions; b Conventional; c, d SSS, nondiagonal noise covariance matrix; e, f SSS, diagonalized noise covariance matrix; c, e SSS (n int, n ext) = (7, 3); d, f SSS (n int, n ext) = (12, 3)
