Weight-and Layout-Optimized Sparse Arrays

  title={Weight-and Layout-Optimized Sparse Arrays},
  author={Sverre Holm and Bj\ornar Elgetun and Geir Dahl},
Theory for random arrays predicts a mean sidelobe level given by the inverse of the number of elements. In this paper two optimization methods for thinned arrays are given: one is for optimizing the weights of each element, and the other one optimizes both the layout and the weights. The weight optimization algorithm is based on linear programming and minimizes the peak sidelobe level for a given beamwidth. It is used to investigate the conditions for finding thinned arrays with peak sidelobe… CONTINUE READING
