ABSTRACT:
Eight radiators, disposed along a line, are coupled to a radar via a Butler matrix. In response to a transmitted signal from the radar, inverse transform signals that have amplitudes representative of values of a sinusoid in an angular range of zero radians to .pi. radians is applied to the Butler matrix. The inverse transform signals cause excitation to be applied to two of the radiators that are adjacent to each other. The inverse transform of the sinusoid at the output of the Butler matrix, in addition to allowing the excitation of two adjacent pairs of radiators, also provides a transmitted beam having reduced beamwidth and lower sidelobes. The two adjacent radiators are selected by selecting a phase pattern of the inverse transform signals.
