Abstract : A beam former, to be used with a circular array of N receiving elements, N or = 3, is described which comprises a set of N discrete Fourier transform (DFT) devices, each one connected to one of the receiving elements, for taking a temporal discrete Fourier transform of the signals at each of the N receiving elements. Means are connected to the array of DFT devices, for connecting sequentially to each of the N devices.
