分段Pad逼近法用于預(yù)測二維介質(zhì)柱的單站RCS方向圖

Pad approximation in segments applied to predict monostatic rcs pattern of a 2D dielectric object

  • 摘要: 矩量法與分段Pad逼近法結(jié)合用于預(yù)測任意形狀截面二維介質(zhì)柱的單站RCS方向圖。該方法采用以總電場為未知函數(shù)的微積分方程。在矩量法過程中，用共軛梯度法和快速傅里葉變換(CG-FFT)的組合算法求解線性方程組，以便降低存儲量和加快迭代速度。分段Pad逼近法用于加速獲取單站RCS方向圖。這里為分段Pad逼近法增添了一個自適應(yīng)算法,克服了以往人工選擇展開點位置的缺點，這種新的組合算法稱為CG-FFT-PAIS算法。文中的數(shù)值算例證實了所述方法的有效性和實用性。
    Abstract: The Method of Moment (MoM) in conjunction with Pade Approximation In Seg-ments (PAIS) is applied to predict the monostatic Radar Cross-Section (RCS) pattern of an arbitrarily shaped 2-D dielectric object. In the method, integro-differential equation for the total electric field is used. In MoM procedure, to reduce the need for computer memory and to speed up the iteration, a combined algorithm of conjugate gradient method and fast Fourier transform is used to solve the algebraic system. PAIS is used to accelerate the drawing of RCS pattern. PAIS here is equipped with a procedure for selecting expanding points, and so short-comings of original scheme of man-selecting location of expansion points are overcome. The new method is called CG-FFT-PAIS. Numerical results in this paper demonstrate the validity and the practicability of the method.
