Abstract

The invention discloses an intelligent skin antenna electric compensation method based on an embedded fiber bragg grating. The method is characterized by comprising the steps that the fiber bragg grating is firstly embedded into a skin antenna structure, then sensed strain is converted into deformation displacement through a strain-displacement transfer matrix, finally the excitation current of a skin antenna is modified through sensed deformation displacement, and therefore the aim of the influence of compensation structure deformation on electric performance is achieved. The method has the advantages that the mechanical property of the skin antenna structure can be monitored in real time, health monitoring on the structure is achieved, and the problem that the electric performance of the skin antenna is lowered due to structural vibration and deformation on active service can be solved through the method. A fiber bragg grating sensor is light in mass and can be embedded into the structure, the pneumatic and invisible performance of an aircraft is not influenced, the fiber bragg grating sensor can be applied to the fields of airborne early warning aircrafts, warcrafts, unmanned aerial vehicles, invisible warships and the like, and the key technology for guaranteeing the reliable service of the performance of the skin antenna is achieved.

Description

technical field [0001] The invention relates to an electrical compensation method for an intelligent skin antenna, in particular to an electrical compensation method for an intelligent skin antenna based on an embedded fiber grating, and belongs to the technical field of antennas. Background technique [0002] Smart skin antennas refer to embedding the radio frequency components and sensing elements of integrated antenna arrays into airborne, shipborne, spaceborne and vehicle structures. In service, due to the influence of aerodynamic, vibration, shock or temperature loads, the deformation of the smart skin antenna structure will be caused, which will lead to the degradation of the electrical performance of the antenna. The invention is an electric compensation method proposed for solving the deterioration of the electric performance of the antenna in service. [0003] In related research, NASA has developed a wing for long-range drones, in which the antenna array, solar ce...
