This paper investigates the mapping capabilities of a linear receiving array of acoustic sensor pairs that measure both the pressure and pressure gradient along the array axis. It is demonstrated that unambiguous pressure maps of remote sources can be obtained even if the separation between sensor pairs is one wavelength (twice the spatial Nyquist sampling interval). The effect of additive noise—both correlated and uncorrelated at each sensor pair, but uncorrelated between sensor pairs, is studied and found not to be a major problem. In the second half of the paper an analysis of the cross correlations of the output voltages from the various sensor pairs reveals that each pair providesthreedistinct cross correlations. Accordingly from data obtained from an array with sensor pairs spacedthreehalf‐wavelengths apart an unambiguous map of the source intensity distribution can be formed. Examples of such maps are provided.
