Linear: Broadside null with directivity and taper

This synthesis algorithm will design a linear array that has a broadside null, with a specified directivity either side of the null and excitation taper. The specification of the excitation taper allows the sidelobes to be controlled. This array can be designed with the elements arranged along any of the 3 major axes with the resulting pattern being rotationally symmetric around the chosen axis and the null being in the plane normal to that axis.

An example of a 3D pattern for this array.

The inter element spacing designed by this algorithm will always be 0.5 λ. The excitation taper can be selected between equal excitation [Uniform] and near-in side-lobes at quasi-uniform specified level [Bayliss]. The side lobe level and number of side lobes can be set when using the Bayliss taper.

More information about how the array synthesis tool should be used can be found in the array article in the information browser. This article also describes the different excitation tapers in more detail, and provides references for further research.
