Abstract: Usually, weighted array antennas are designed by using the statistical appro-ach. In this paper, the application of the Markoy chains of a random process to the design of density weighted or phase weighted arrays is considered. The new approach is proposed to improve the Statistical approach and devides the array into several parts, in which the selection of the element location or phase is performed correlatively utilizing the probability density function for specifying the location or phase of elements at every part.
