Space time adaptive processing using real array elements based on direct data domain adaptive nulls genetic algorithm beam forming

This paper presents a new direct data domain adaptive nulls genetic algorithm beam forming approach to space time adaptive processing. The proposed approach performance will be tested using uniformly spaced real antenna array elements; hence the received signals at the array elements will be affected by the mutual coupling. The method of moments is used to evaluate the mutual coupling between the elements of the given array and then the transformation matrix method will be used to compensate for these undesired mutual coupling effects. The matrix pencil method will be used to estimate the direction of arrival as well as the magnitude, of all coming signals. Finally, the genetic algorithm will be used for array beam forming and the formed beam pattern capability to reconstruct the signal of interest will be investigated.
