摘要

给出了在不同的变分公式下,按照规定的振幅指向性图(DP)研究平面辐射孔径合成天线问题的结果。解的非唯一性和分支性是这类问题的特征。叙述了根据孔径大小和规定振幅DP的性质求解分支线的方法;给出了求解综合问题最优解的合理算法。结果表明,与同相DP类的合成相比,找到最优相位DP可显著提高合成DP对规定值的逼近质量。特别是,它允许在相同的合成效率下减少天线孔径的尺寸,与同相DP的合成相比,减少了近30%。

The mathematical features of the synthesis of antennas with a flat aperture according to the prescribed amplitude directivity pattern
The results of investigations of synthesis antennas problems with a flat radiating aperture according to the prescribed amplitude directivity pattern (DP) in the different variational formulations are presented. The non-uniqueness and branching of solutions are characteristic for problems of this class. The methods for finding the branching lines of solutions dependent on the sizes of the aperture and properties of the prescribed amplitude DP are stated; justified algorithms for finding the optimal solutions of synthesis problem are presented. It is shown that finding the optimal phase DP improves significantly the quality of the approximation of synthesized DP to the prescribed in comparison with synthesis in the class of in-phase DP. In particular, it permits to decrease the sizes of antenna aperture at the same efficiency of synthesis in comparison to synthesis in the class in-phase DP nearly per 30%.
