The challenge with the formation of sparse antenna arrays is to arrange the array elements along the aperture in order to provide a beam pattern with the required characteristics. It is proposed to use Costas arrays to form sparse antenna arrays. The width and shape of the beam pattern formed on the basis of Costas matrices coincide, on average, with the width and shape of the beam pattern of an equidistant planar antenna array. Choosing the size of the Costas matrix makes it possible to provide the required sparsity factor and the concentration coefficient, and the introduction of tapered amplitude distributions controlling the sidelobe level. The concentration coefficient of a sparse antenna array does not practically depend on frequency. Two methods are arrays with high sparse factors, the second one allows forming sparse antenna arrays with low sparse factors.
