| 摘 要： | 本文针对目标散射体表面感应电流的特性，提出了一种新的插值方法—幅相分离法，该方法将最佳一致逼近和相位提取结合起来，通过求解给定频带内的切比雪夫节点和节点处的表面电流，结合相位提取得到整个频带内的感应电流，从而快速有效地计算了复杂目标的宽带雷达散射截面。数值结果证明了方法的有效性和准确性。

| Abstract: | The characteristic of surface electric currents on conducting objects is presented in this paper.A new interpolation theory(Amplitude-phase detached interpolation) is introduced.The best uniform approximation in conjugation with the phase extracted is applied to the conventional high-frequency method,The nodes of Chebyshev within a given frequency range were found firstly,and the surface electric currents at these nodes were computed by the conventional high-frequency method.Then the electric current distri... |
