APPENDIX 12A: AN EQUATION FOR TAYLOR WEIGHTS

The following are equations for calculating Taylor weights for an array antenna. It is similar to the equation on page 20-8 of the Antenna Engineering Handbook by Richard C. Johnson [14], with some clarifications and corrections.

The un-normalized weight for the nth element of the N-element linear array is

where

and

SL is the desired sidelobe level, in decibels, relative to the peak of the main beam and is a positive number. For example, for a sidelobe level of −30 dB, SL = 30. This indicates that the sidelobe is 30 dB below the peak of the main beam. is the number of sidelobes on each side of the main beam that we want to have a level of approximately SL below the main beam peak amplitude.

The xn can be computed using the following MATLAB notation:
