| 摘 要： | 文章介绍了基于应变测量的卫星天线变形检测方法。该方法针对卫星天线在实际工作中产生的阵列形变，应用弹性力学的有关理论和解析方法，通过测量天线阵列单元面板表面的应变数据推导并拟合出天线阵列弯曲的挠度函数，绘制出天线阵列单元的变形构型。实验表明，该方法有较高的精度，能够为天线输出信号的相位校正控制提供依据。

| Abstract: | A new displacement detection method for the satellite phased-array antenna based on the strain measurement is proposed. To obtain the displacement of the antenna panel, the panel bending function and the distortion distribution curve are derived based on the theory of elasticity and according to the strain data on the surface of the phased-array antenna panel. The experimental results demonstrate that this method can provide a basis for the phase correction control of high accuracy. |
