In this paper, it is illustrated on how to carry out adaptive processing simultaneously at multiple frequencies using the same antenna array consisting of dissimilar antenna elements nonuniformly spaced and deployed in any environment. First, a transformation method is introduced to account for all non-ideal effects of an antenna deployed in a real environment, such as mutual coupling between the...
This paper illustrates a method to carry out adaptive processing simultaneously at multiple frequencies using the same antenna array located over imperfect ground planes. First, it is shown how to transform an array situated over an imperfect ground to a uniformly spaced array of point radiators. Then, a direct data domain least squares (D3LS) method is used to extract the signal-of-interest (SOI)...
This paper introduces an anti-jamming technology for satellite communication that can cancel terrestrial jammers. In this paper, we first consider the Conjugate Gradient Method (CGM) as the first adaptive algorithm. Using this method, the attainment of the depth of the nulls and the rate of convergence are shown to be excellent. We also introduce a second novel adaptive algorithm, the hardware complexity...
The objective of this presentation is to describe a general methodology for adaptive processing using conformal arrays for a single snap shot of data and without any statistical assumption on the noise and the interferences. The antenna elements in a conformal array can be unequally spaced and they need not be situated over a planar surface. In addition the antenna elements can have a directive gain...
