Plot Array Directivity Using Sensor Array Analyzer App
sensorArrayAnalyzer app lets you examine important properties of a phased array such as its shape and directivity.
Open sensorArrayAnalyzer App
When you type
sensorArrayAnalyzer from the command line or select the app from the App Toolstrip, an interactive window opens. The default window shows the geometry of a 4-element uniform linear array. You can then select various options to analyze different arrays, other element types, geometry, and directivity.
Create 3D Directivity Plot of 4-by-4 URA
As an example, use the app to create a 4-by-4 uniform rectangular array of cosine antenna elements and then show the array directivity. Space the elements 0.4 wavelengths apart.
Set the Array to
Set the Element to
Set the Size of the array to
Set the Element Spacing to
[0.4 0.4]. Set the element spacing units to wavelength.
Set Propagation Speed to
From the Steering pull down menu, set the Steer Angle to
[-30,0]to steer the array -30 degrees in azimuth.
In the Plot menu, select
Then, you will see a plot of array directivity similar to this.
