The planar near-field calibration array (NFCA) was developed by Trott [W. J. Trott, Underwater Sound Ref. Rep. No. 55 (1961); also J. Acoust. Soc. Am.36, 1557–1568 (1964)] for use in determining the far-field acoustic radiation from underwater transducers by measurements in the near field. As a projector, the NFCA produces a nearly uniform plane wave over a large volume in its near field and over a large frequency range. As a receiver the NFCA acts like a plane-wave filter for acoustic radiation (or target scattering) originating from within the plane-wave volume. Thus the NFCA can be used to determine the far-field performance of both receiving and projecting transducers. In addition, it can be used to insonify nearby targets with plane waves and determine the resulting scattered far-field pressure. Earlier papers concentrated on the geometrical design of NFCA’s and the computation of their relative element responses (or sensitivities) for a specified array configuration, near-field volume, and frequency range. This paper provides analytical expressions for the near-field transmitting voltage and current responses and near-field receiving voltage and current sensitivities of a planar NFCA. The paper also provides information to aid in the NFCA element selection process, especially with regard to shading of the NFCA.
