Space-time adaptive processing for airborne radar: A convenient implementation approach

A convenient implementation approach to space-time adaptive processing for airborne radar has been proposed, which is added by some auxiliary array elements in the area of main-lobe clutter on the basis of 2-D Capon approach. It is of practical use for its small computational load. This approach possesses the ideal performance in the area of main-lobe clutter. In addition, the approach which is added by some auxiliary beams in the area of main-lobe clutter has also been discussed.
