Intelligent skin antenna electric compensation method based on embedded fiber bragg grating

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.
