Array Geometries and Analysis

Phased arrays consist of antenna or microphone elements arranged into regular patterns. Common array types include uniform linear arrays, uniform rectangular arrays, and uniform circular arrays. You can also build arrays with arbitrary geometries by using conformal arrays. For many examples of the kinds of arrays that the toolbox supports, see Phased Array Gallery. The toolbox includes System objects for building arrays composed of subarrays and partitioned arrays. You can model array perturbations and mutual coupling between elements and create heterogeneous arrays with different element types. You can incorporate Phased Array System Toolbox™ or Antenna Toolbox™ antenna elements in your arrays. Methods let you plot array directivity and other radiation patterns. You can also create and use steering vectors for dynamic array pointing. You Differential weights can create frequency-invariant beam patterns and are often used in microphone arrays.
