The communication may be between the antenna ar WI rays of an airborne platform (such as aircraft) and a surface base station. The antenna arrays may generate a plurality of directional N synchronization beams directed in at a plurality of corresponding spatial directions. Other antenna arrays receive the directional w• synchronization beam and respond in kind, providing the original antenna array a way to determine directionality of the other an tenna arrays. The antenna arrays may then receive a training beam. The training beam includes known data, such as a Fourier Ma trix, which may then be utilized to generate weights. Weights may then be utilized to modify either of the phase or amplitude of ao base sipal which is then sent to each of the elements of the antenna array in order to achieve directionality of the signal propaga ri tion. Thus, a directional beam may be formed which is oriented toward the source of the training beam, which may be a base sta Qtion or the like. It may also be desirable to identify sources of interference. Interference sources are all non-desired sources of radi `,t ation within the target frequency range. Lastly, the system may steer one or more nulls in order to substantially attenuate thesources of interference.
