Optical sensor for the management of Radar antenna distortion

摘要

Electronically steered antenna quality mainly relies on the accurate periodicity of the radiating element positions. Very thin antenna with non-rigid structures will permit the implementation of disruptive mechanical designs and provide better tactical deployment and permit implementation on non-dedicated platforms. To maintain planar antenna performances, we propose to dynamically cope with distortions with an innovative method. In this presentation, we will report on an innovative real-time and embedded measurement technique in harsh environment based on an optical polarization sensor coupled with an adapted mechanical model, designed in order to maintain a sufficient calibration of the antenna during its operational use.
