Abstract : This paper discusses several methods of optimizing the pattern of a phased array antenna. Two methods, the gradient search algorithm method and the null displacement technique were shown to be applicable to optimizing a phased array with failed elements. The results of the study show how the pattern can be optimized depending on the scalar cost function and constraints chosen and what effects varying the complex weight of the array elements has on the pattern.
