A multi-aperture array antenna provides a narrow beam width, low side lobe radiation pattern for an illuminating beam through the forward feed of a ladder-type feed structure. Alternatively, the rear feed of the ladder network is so electrically tapered as to provide three simultaneous low side lobe smaller apertures which can be independently directed via phase shifters to provide distinct received beams for interferometric phase comparison. A feed connected to one radiating element in each of the three apertures form a broad-beam pattern for side-lobe ...
An array antenna capable of sequentially operating in either a transmit mode and one of several receive mode, comprising: means including a plurality of array elements disposed in a planar configuration, said array elements being positioned in at least one laterally extending row, adjacent ones of said array elements being separated by a distance corresponding to about one-half of the wavelength (l0/2), of said radar signals; phase shifting means connected to each one of said plurality of array elements for directing the beam of said antenna in said tran...
