摘要

共享孔径交错稀疏阵列天线是实现多功能阵列天线的有效途径。现有的参数化互耦消除方法都是针对均匀阵列天线展开的，其研究的互耦矩阵都是规则的方阵，对共享孔径交错稀疏阵列天线的互耦矩阵模型并不适用。在充分考虑共享孔径交错稀疏阵列天线中子阵内互耦的“稀疏”和“方位依赖”的特殊性后，通过将常规的互耦矩阵扩展表示为“非方”的“增广互耦矩阵”来对交错稀疏阵列天线子阵内和子阵间的耦合效应进行建模，并通过“增广互耦矩阵”的参数化估计最终实现了共享孔径交错稀疏阵列天线互耦误差的建模与校正。仿真结果证实了所提方法的有效性和可行性。

Abstract

The shared aperture interleaved sparse array antenna is an effective way to implement a multi-function array antenna.The existing parameterized mutual coupling elimination methods are all developed for uniform array antennas.The mutual coupling matrix which is studied is a regular square matrix and is not applicable to the mutual coupling matrix model of the shared aperture interleaved sparse array antenna.After fully considering the speciality of “sparse” and “azimuth dependence” of mutual coupling in sub-arrays of a shared aperture interleaved sparse array antenna

the conventional mutual coupling matrix extension was expressed as “non-square” “enhanced mutual coupling matrix”.Coupling effects between subarrays and subarrays in interleaved arrays of sparse arrays were modeled

and the modeling and correction of mutual coupling errors in shared aperture sparse array antennas were finally achieved through the parameterization of “enhanced mutual coupling matrix”.Simulation results verify the effectiveness and feasibility of the proposed method.
