An ambient acoustic field is assumed to be observed through a delay‐and‐sum beamformer, in conjunction with a line array of non‐uniformly‐spaced sensors. The beamformer output power, as a function of steering direction, is related to the angular power density of the acoustic field through a certain integral equation, with the kernel being the known power response pattern of the array. In this note, we present the results of some computer experiments concerned with solving this integral equation by working directly in the angle domain, rather than in the wave‐number spectral domain. The method is general for any array, but is of interest mainly in the case of a non‐uniformly‐spaced array, to which our examples correspond.Subject Classification: [43]60.20, [43]60.30; [43]30.82.
