| 摘 要： | 将MDMEI引入平面相控阵天线的分析与设计算法之中,通过选择适当的测试函数(Metrons),成功地实现了矩阵方程中满系数矩阵的分解与高度稀疏化,其稀疏率不超过4.1%.方向图的数值计算结果表明,除H平面极远区个别副瓣以外,MDMEI结果具有良好的精度.该技术可以显著提高相控天线的优化设计效率.

| Abstract: | Matrix decomposition by measured equation of invariance (MDMEI) is introduced into the algorithm of analysis and design of planar phased arrays. By suitable selection of metrons (the measured functions in the MEI terminology), the coefficient matrix in the matrix equation is successfully decomposed and highly thinned down, where the sparsity rate is no more than 4 1%. The numerical results of the radiation patterns show that MDMEI results have rather high accuracy except for some individual farthest sidelobes in the H Plane. This matrix decomposition technique will increase significantly the optimization design efficiency of phased array antennas. |
