摘要

针对交集法下卫星反射阵列天线的纯相位合成过程，提出了交替广义投影法（AGP）的可行算法。这种有前途的算法是文献中救助的两种非凸集合专门算法的混合算法：基于分离超平面的算法和基于极锥分解法的算法。由于卫星反射阵列天线的纯相位合成过程所涉及的集合是非凸的，文献中提出的传统冯-诺依曼交替投影法不能保证收敛到所涉及集合的交点。此外，还比较了不同算法得到的纯相位合成结果，并显示了所提出的混合算法所带来的可喜改进。

Alternating generalized projection method applied to phase-only synthesis process of satellite reflectarray antennas

Promising algorithm of alternating generalized projection method (AGP) is proposed for phase-only synthesis process of satellite reflectarray antennas under intersection approach. This promising algorithm is a hybridized algorithm of two specialized algorithms for non-convex sets rescued in the literature: algorithm based on separating hyperplanes and algorithm based on decomposition method in polar cones. Since the sets involved in phase-only synthesis process of satellite reflectarray antennas are non-convex, the conventional von Neumann alternating projection method proposed in the literature does not guarantee convergence to the point in the intersection of the involved sets. In addition, the results of the phase-only synthesis obtained by the different algorithms were compared and promising improvements produced by the proposed hybridized algorithm were shown.
