dimension select
2.Among all kinds of errors presenting iuevitablely in actual filtering systems, the clement amplitude and phase errors which are hard to be corrected in advance attenuate the clutter suppression performance of the (himueulsioll-reduce(l STAP approaches more seriously. how to select the additiona.I spatial channels suited to improve the ability to correc errors of those dimension-reduced STAP approaches is discussed preliminarily.
