A pragmatic approach to adaptive antennas

This paper presents a novel approach for efficient computation of adaptive weights in phased-array antennas. The fundamental philosophical differences between adaptive antennas and adaptive signal-processing methodology are a lso delineated in the introduction. This approach, unlike the conventional statistical techniques, eliminates the requirement for an interference cova riance matrix, and represents a rethinking of the entire conventional appro ach to adaptive processing. This approach provides greater flexibility in s olving a wider class of problems, at the expense of a slightly reduced numb er of degrees of freedom. It is important to note that the application of a deterministic approach to address stochastic problems with an ergodic stru cture can be seen in the works of Norbert Wiener and A. N. Kolmogorov, as o utlined in the introduction. This paper presents examples to illustrate the effectiveness and uniqueness of this new pragmatic approach.
