Abstract
A numerical procedure based on a genetic algorithm is proposed in order to synthesize a linear, sparse, and aperiodic array to be used in a beamforming processor. The method is aimed to minimize the sidelobe peak of the beam pattern acting on the elements' positions and weights. Obtained results also confirm the effectiveness of the approach in comparison with other techniques in the related literature.βΒ© 2002 John Wiley & Sons, Inc.

Interruptions in the regular lattice of a phased array antenna can lead to elevated sidelobe levels in the resulting antenna pattern. A method for reducing the sidelobe level in such an array is presented, based on the use of a genetic algorithm that modifies the element weights in the array. Result
## Abstract A method of minimizing the sidelobe level for linear array patterns by amplitudeβonly adjustment in element excitations, which involves combining Bβspline techniques and genetic algorithms, is considered. We demonstrate this technique using a 30βelement linear array. It is also capable
