WebCylinder in Cylindrical Track Angular Natural Frequency Equations and Calculator Machine Design and Engineering ω n = [ ( 2 g ) / ( 3 * ( R t - R c ) ) ] (1/2) WebDec 7, 2024 · In this paper, a novel near-field to far-field transformation method with bistatic RCS measurement is proposed. First, the RCS measurement is perceived as a double radiation model. Doing this, the relationship of near-field data and far-field data at different angles is derived, and the convolution function is given under the cylindrical wave.
