| dc.description.abstract | The implementation of code to efficiently compute the array factor and sidelobe level (SLL) of linear antenna arrays in MATLAB and GNU Octave is considered. The use of a fast Fourier transform (FFT) to compute the array factor is shown to be more efficient than other approaches. The automatic determination of the sidelobe region as a necessary step to computing the SLL is addressed. A number of codeoptimsation techniques in MATLAB and Octave are evaluated, including vectorisation, memory allocation and the use of built-in functions. Finally, an efficient function which can be used for the computation of the array factor and SLL of linear arrays in MATLAB and Octave is presented. | en_ZA |
