A Clonal Selection Algorithm for Array Pattern Nulling by Controlling the Positions of Selected Elements

Abstract

Abstract-In this paper, a method based on clonal selection algorithm (CLONALG) is proposed for null steering of linear antenna arrays by controlling only the positions of selected elements. The CLONALG is a relatively novel population-based evolutionary algorithm inspired by the clonal selection principle of the human immune system. In order to illustrate the accuracy and flexibility of the proposed algorithm, several numerical examples of Chebyshev pattern with the single and double nulls imposed at the directions of interference are given.

Pattern nulling of linear array antennas with mutual coupling effects using taguchi method

“…If the array elements are symmetrically situated and excited around the center of the linear array, the far field array factor of such an array is real, and can be written as [1]:…”

A Clonal Selection Algorithm for Classification of Mangroves Remote Sensing Image

“…As a kind of artificial immune algorithm, clonal selection algorithm is derived from the clonal selection principle [11]. Clonal selection principle simulates b cells protect the human body against attacks from antigens (such as viruses, bacteria and other parasites) and eliminate the infected cells.…”

Pattern Synthesis of Planar Antenna Array via Convex Optimization for Airborne Forward Looking Radar

“…A lot of methods have been developed for the synthesis of the linear and planar arrays [7,8]. In particular, the techniques of placing nulls in the antenna patterns are given in the literature [9][10][11]. Most of these methods optimize only one parameter and are not suitable for the synthesis of airborne forward looking planar antenna.…”
