Abstract
This radiating-element array antenna has its radiating elements grouped together, in reception, in two sets of parallel linear sub-arrays imbricated and oriented in the two directions, namely the horizontal and vertical directions. It comprises two beam-shaping circuits each receiving the signals from one of the sets of linear sub-arrays and carrying out two reduced beam-shaping operations, one in the elevation plane and other in the relative bearing plane, and one output circuit delivering a reception signal from a non-linear combination, a product or convolution, of the two reduced beam-shaping signals generated by the beam-shaping circuits. This reception signal simulates the signal of an antenna with total beam-shaping in the two planes, namely the elevation and relative bearing planes.
