Abstract :
The authors demonstrate that the ALPINEX technique is applicable to the circular array case and by simulation explore some of the areas of interest. In particular it is indicated that the deleterious effect of nulls in the Bessel weighting factors can be mitigated by the interpolation facility in ALPINEX. The presence of a central element in the circular array is advantageous
