Abstract:The impact of the parameters such as element spacing, source frequency, array forms of phase conjugation arrays consisting of discrete elements are investigated numerically for sound source localization on the field magnitude and the spatial size of the conjugated field. The results show that the element spacing should be less than 0.5   to break the diffraction limit with the planar array only made of dipole transceivers in the near field and the optimal element spacing is 0.15  . With increasing frequency the field magnitude increases and the spatial resolution decreases. Regarding to the number of array elements and the performance the optimal array form is the criss-cross array with fewer elements.
