摘要
将投影迭代法应用于分析任意二维和三维电大导体目标的电磁散射特性。该方法首先剖分传统矩量法得到的矩阵方程 ,然后通过投影迭代逐步修正未知电流值 ,进而计算目标的雷达散射截面。数值计算表明 :该方法与传统矩量法计算结果相吻合 ,计算量大大降低。
The projection iterative method (PIM) is used to analyze electromagnetic scattering characteristics of two dimensional and three dimensional electrically large conducting objects in this paper. Integral equations can be reduced to algebraic linear equations by using the method of moments, the impendence matrix is divided into a series of small sub regions by decomposition. The surface currents of objects can be computed by the PIM iterative process, and the radar cross section can also be achieved. The numerical results are in good agreement with the results obtained by the method of moments, and the computation effort are considerably reduced by PIM.
