Abstract
The problem of performance increasing of a small measurement array in the task of single narrowband source localization in the nearfield is considered. Two different approaches for acoustic field interpolation in combination with a conventional acoustic holography are proposed. One of them, based on the autoregressive model of a sinewave, gives better resolution in localization of the source near the center of the array. The second one, based on the estimation of instantaneous phases of signals from each microphone, decreases error of peak localization from sources near the boundaries of the measurement array.
