Abstract

In this paper, it is illustrated how to carry out adaptive processing simultaneously at multiple frequencies using the same antenna array consisting of dissimilar antenna elements nonuniformly spaced and deployed above an imperfect ground plane. First, an electromagnetic transformation technique is described which can compensate for all non-ideal effects of an antenna array deployed in a real environment, such as mutual coupling between the elements, the presence of an imperfect ground, etc. Then, a direct data domain least squares method is used to extract the signal-of-interest (SOI) in the presence of jammer and clutter simultaneously at multiple frequencies, using a single snap shot of the data. The interferers/jammers can come from multiple directions, frequencies and can even be non-coherent.
