Mutual coupling error modeling and correction of shared aperture interleaved sparse array antennas
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...

| description | 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. |
