Design of sparse arrays with high sidelobe rejection

An approach to the design of one-dimensional sparse arrays based on the factorization of a polynomial representation of the effective aperture function is outlined along with algorithms for designing arrays with staircase, mixed linearly tapered and staircase effective aperture functions. It is also shown that a combination of linearly tapered and staircase effective aperture functions results in sparse arrays with higher side lobe rejections and slightly smaller element reduction factors than that obtained in sparse arrays with staircase effective aperture functions.
