摘要：
Mechanical distortions on large active antenna structure entails significant degradations of their radiating pattern, and consequently on radar performances. In this paper, we propose to dynamically cope with distortions with an innovative two-step method. First, the antenna shape is measured via a series of optical sensors distributed on the antenna; afterwards the global radiating pattern is reshaped using a computed phase law applied on the radiofrequency signals of each radiating element. © 2011 Lavoisier, Paris.
