Abstract

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.

Description

technical field

[0001] The invention relates to the technical field of array antennas, in particular to an array antenna with fast self-repair capability and a self-repair method thereof. Background technique

[0002] Array antennas are widely used in modern radar equipment due to their high power, high gain, and fast beam scanning. Array antennas are usually composed of a large number of array elements, and through the amplitude and phase changes of the excitation signal of each array element, high-power, high-gain, and different-directional beams are synthesized in the air. A large number of array elements is the basis of array antennas, and the increase in the number of array elements also increases the probability of failure of array elements.

[0003] The structure of the array antenna is complicated, and the failure of the array element is not easy to replace and repair. Especially in application environments such as aerospace and battlefield, it cannot be repaired i...
