Dolphchebyshev
WebThe question of optimality Dolph-Chebyshev amplitude distributions of linear antenna arrays by the criterion of maximum aperture efficiency for given side-lobe level is considered in this article. It is shown that the beam width is not necessarily uniquely related to the magnitude of the aperture efficiency. This fact is physically justified. It based on the ratio … Webthe Dolph–Chebyshev or, for short, Dolph window. This window may be used to modify the coefficients of a low-pass filter, as was done with the Lanczos window in LH92, to reduce Gibbs oscillations. Alternatively,the window may be used directly as a low-pass filter, as will be described below. 3. Design of low-pass filter
