ABSTRACT OF THE DISCLOSURE A receiving system includes a linear array of receivers, each of which is responsive to incident stimuli for producing an output signal, and signal processing means for processing the output signals to provide the array with pre-selected directional rejection characteristics. Such processing includes obtaining sum and difference signals from the outputs of pairs of the receivers, integrating the difference signal, and combining the integrated signal with the sum signal such that stimuli incident on the array at a predetermined angle and at a predetermined frequency are substantially rejected. The angle and frequency at which rejection takes place are selected on the basis of the spacing between the pairs of receivers whose outputs are added and subtracted, and on the basis of the relative gain applied to the integration and sum signals before they are combined.
