ABSTRACT:
A coded linear array antenna comprised of a plurality of multiple element barrays, each providing sin mx/sin x patterns which are combined, i.e. summed into a composite pattern by having the subarrays commonly connected to a signal summation means. Each subarray is comprised of multiple elements which are respectively spaced equidistantly apart and positioned symmetrically on either side of a common array axis center or axis of symmetry and wherein the individual antenna elements of each subarray are positioned at an i.sub.th location according to the normalized equation ##EQU1## where i=1, 2, 3, . . . h, n.sub.m defines the maximum number of elements in the length or aperture of the composite array, h is the number of elements in the respective subarray, and n is proportional to the element spacing of the respective subarray.
