交叉极化及副瓣约束的任意阵列最优方向性综合
Optimal Directivity Synthesis of an Arbitrary Array Subject to Sidelobe and Cross-Polarization Constraints
摘要
Abstract
Definitions of the desired co-polarization and cross-polarization directions are given for a scanned beampattern according to a desired polarization direction.Furthermore,the co-polarization directivity is defined to more accurately represents the degree of the concentration of co-polarization field over the total radiated power.With this definition,the co-polarization directivity can be optimized.Its analytical expression can be derived when no more pattern constraints exist.In more general cases in which the constraints on the sidelobe level,nulling points and cross-polarization level exist,an efficient numerical algorithm based on convex optimization is proposed.Some numerical synthesis experiments are conducted,and the results show the effectiveness and robustness of the proposed synthesis techniques.关键词
