Our goal now is to determine the response of the array when steered towards , when the weights are chosen using the equation above. Using the definition of the array factor, we can write: The above can be simplified by recalling the definition of the wave vector: Substituting the above ...
In the remaining part of this work, we usefP(x) = [ff(x)TfL(x)T]T, whereff(x) = [ff.1(x) …ff.K(x)]TandfL(x) = [fL.1(x) …fL.K(x)]T, to denote a response feature vector, its horizontal and vertical coordinates, respectively. The feature-oriented merit ...
