Phased Array System Toolbox

Phased Array Design and Analysis

Phased Array System Toolbox enables you to model and analyze the behavior of common array geometries and user-defined array geometries. Common array geometries include:

  • Uniform linear array (ULA)
  • Uniform rectangular array (URA)
  • Conformal array

You can define your own array geometry by specifying the number of elements, the element spacing, and each element’s position and orientation in 3D space. The individual element response and radiation pattern can be isotropic, cosine shaded, or specified by your own 3D pattern. Your response and radiation pattern can be either described by an ideal analytic function or defined from measured data. You can apply shading (tapering) across the entire array.

You can also define multiple element patterns in an array to model an inhomogeneous array.

With the system toolbox, you can model common antenna and microphone elements. In a custom antenna or microphone, you can specify wideband, frequency-dependent patterns. You can also specify polarization in polarization-capable antenna elements, such as Dipole or custom antennas.

The system toolbox provides tools to visualize and analyze the radiation pattern of individual elements or of the whole array in aggregate. The visualization can be inspected in rectangular, spherical, and u/v space. With the tools, you can measure or visualize:

  • Array geometry
  • Array gain
  • Array response
  • Delay between elements
  • Steering vector
  • Element response
