Improved array configurations for synthetic aperture interferometric radiometers

Minimum redundancy linear arrays permit the maximum number of antenna elements to be removed from an imaging interferometer. Exact solutions are known for the locations of the elements in small arrays only. A new algorithm is presented which constructs arrays with fewer redundant samples than other procedures. At present, these arrays provide the best angular resolution for a given number of elements and they provide a given angular resolution with the fewest elements. Some implications of these array configurations on the design of high resolution imagers is discussed.<
