Abstract :
In practical situations, it is necessary to have a flexible methodology for adaptive processing that can deal with the effects of mutual coupling between the various antenna elements, the coupling between the antennas and the platform and. the effects of near-field scatterers. To merge the signal processing and the electromagnetics methodology with the goal to deploy it in a real system containing practical antenna elements, we propose to use a direct data domain approach for adaptive space-time processing which is quite amenable to real time processing. In this approach one adaptively minimizes the interference power while maintaining the gain of the antenna array along the direction of the signal. We illustrate the problem through an example and this also provides a cursory overview of the technique.
