Array antenna with fast self-repairing ability and self-repairing method thereof

The invention discloses an array antenna with a fast self-repairing ability and a self-repairing method thereof, and relates to the technical field of array antennas. The array antenna comprises an array element array, a T/R cell array, a power distribution/addition network and a beam control system, wherein the T/R cell array includes an input switching control module, k T/R cells, a detection module and an output switching control module. The array antenna can realize fast self-repairing thereof through fast switching of the T/R cells on the basis of fast self-detection, the original state of each radiation array element signal is maintained in the self-repairing process, the mutual coupling between the array elements does not change, and the self-repairing effect is improved. 本发明公开了一种具有快速自修复能力的阵列天线及其自修复方法，涉及阵列天线技术领域。所述阵列天线包括阵元阵列、T/R细胞阵列、功率分配/相加网络以及波束控制系统，所述T/R细胞阵列包括输入切换控制模块、个T/R细胞、检测模块以及输出切换控制模块。所述阵列天线在快速自检测基础上，通过T/R细胞的快速切换，可实现阵列天线的快速自修复，且在自修复过程中，保持了各辐射阵元信号原状态，阵元间互耦不发生变化，提高了自修复效果。
