Abstract:
1. A two-dimensional sparse interferometric array for determining an angle of approach of an incoming signal incident to the array, comprising: a first plurality of elements in a first sub-array and a second plurality of elements in a second sub-array, the first sub-array having a size different from a size of the second sub-array and no three of the first and second pluralities of elements being co-linear, the first and second pluralities of elements forming a plurality of pairs of elements, a configuration of the first and second sub-arrays satisfying a genetic fUzzy optimization algorithm for antenna array design based on a specific set of criteria; wherein the configuration of the first sub-array and the configuration of the second sub-array of elements minimizes a number of elements in the array and provides an unambiguous estimate of an angle of approach of the signal.
