Sensor array analyzer


You use the Sensor Array Analyzer app to construct and analyze common sensor array configurations. These configurations range from 1-D to 3-D arrays of antennas and microphones. You can use this app to generate the directivity of the following arrays.

Uniform Linear Array (ULA)Uniform Rectangular Array (URA)
Uniform Circular ArrayUniform Hexagonal Array
Circular Plane ArrayConcentric Array
Spherical ArrayCylindrical Array
Arbitrary Geometry 

Each array type has different sets of parameters for its specification. After you select an array type, you can modify the array parameters. The parameters you can set include the type of antenna or microphone elements, the number and spacing of elements, and any array tapering (also called shading). You can enter the element spacing in meters or units of wavelength. After you enter all the information for your array, the app then displays basic performance characteristics, such as array directivity and array dimensions.

These are the types of elements available to populate an array.

Isotropic Antenna
Cosine Antenna
Omnidirectional Microphone
Cardioid Microphone
Custom Antenna

The Sensor Array Analyzer app lets you produce a variety of plots and images. These are types of plots available.
