	天线阵面变形是影响雷达电性能关键因素，准确地感知天线阵面形状是实现电性能有效补偿的基础。本文介绍了光纤光栅应变传感器测量方法，建立了影响测量准确度的粘接材料应变传递效率模型。基于模态法形变重构方程，提出一种两步序列传感器布局方法。通过引入有限的实验模态信息和局部对应原理，得到更加贴近实际的模态信息，提出了基于模态法的天线阵面变形重构方法，并设计了天线阵面变形重构实验系统。本文为复杂载荷环境下雷达电性能主动补偿提供了技术支撑。<br />
Antenna array deformation is a key factor affecting the radar electrical performance, and accurately sensing the antenna array shape is the basis for effective compensation of electrical performance. In this paper, the measurement method of fiber Bragg grating sensor is introduced, and the strain transfer efficiency model of adhesive material which affects the measurement accuracy is established. Based on the deformation reconstruction equation of modal method, a two-step sequential sensor placement method is proposed. By introducing the limited experimental modal information and the local correspondence principle, the more practical modal information is obtained. The antenna array deformation reconstruction method based on the modal transmission is proposed, and the antenna array deformation reconstruction experimental system is designed. This paper provides technical support for active compensation of radar electrical performance under complex load environment.
