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.

- 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.
- Polarized Fields
Polarized electromagnetic fields.
- Element and Array Radiation and Response Patterns
Radiation patterns describe fields radiated by antennas and transducers and can be used to analyze directivity and gain.
- Units of Measure and Physical Constants
Phased Array System Toolbox uses the International System of Units (SI).
- Standards and Conventions
This section introduces the concept of baseband signals and defines the local and global coordinate systems used in the toolbox.
