Array Geometries and Analysis

Uniform linear arrays (ULA), uniform rectangular arrays (URA), uniform circular arrays (UCA), conformal arrays, subarrays, array response, steering vectors

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, seePhased Array Gallery．工具箱包括建筑的系统对象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.

Topics

Phased Arrays

  • Uniform Linear Array
    Uniform linear arrays consist of antennas or microphones equally spaced a long a straight line.
  • Uniform Rectangular Array
    Uniform rectangular arrays consist of antennas or microphones placed on a regular 2-dimensional grid.
  • Conformal Array
    Antennas and microphones in conformal arrays can be placed anywhere in three dimensions.
  • Subarrays Within Arrays
    Subarrays are collections of elements within a larger array that can be processed as a group.
