A Randomwalk Bearformer based on phase analysis that has the capability to reduce the grating lobes is presented. This paper analyzes the bidimensional array design process under the perspective of the Randomwalk analysis. The study has been applied to matrix and spiral array distributions. Finally, some solutions based on the Fermat Spiral Array are proposed and evaluated to show their strength against grating lobes.
