Array Optimization Using Subarrays.

Abstract

The concept of directivity index with beamwidth control (DIBC) leads to a practical method for the selection, or optimization, of element excitations to control beamwidth and sidelobe level in a discrete array of arbitrary configuration. This optimization procedure depends upon the design frequency, the specified element positions, individual element field patterns, and the ambient noise field. Each of these factors can be specified in a completely general manner. In addition, the optimization procedure may be adapted to computers of modest memory size. Examples are included to show the versatility of this approach to the optimization problem, as well as its limitations.(Author)
