Abstract
Under certain conditions, it is shown that adaptive arrays with up to six spatial dimensions (three on transmit and three on receive) can provide vast improvements in auroral-zone clutter suppression capability compared to one-dimensional adaptive receive arrays. The required conditions are that the array manifold vector and its associated clutter covariance matrix are factorable into the n-fold Kronecker product of the corresponding quantities for a one-dimensional linear array. When these conditions are satisfied, the overall system signal-to-clutter ratio (SCR) improvement scales with the nth power of the SCR improvement of a one-dimensional linear adaptive array. Some supporting experimental results are provided.
