Abstract:

To precisely control the microwave’s position parameters, the relational expression between driving motor’s displacement and mirror’s rotating angle as well as the relational expression between mirror’s rotating angle and microwave’s launching angle has been calculated. The relationship curves were also given. In addition, the determination experiment has been carried out to mark the position of launching microwave, and the result showed these relational expressions are accurate, and can be the theoretical foundation of the plane mirror’s rotating mechanism’s driving control.

摘要：

为准确控制天线发射微波的位置参数，分析计算了天线平面镜转动机构上驱动电机位移与平面镜转动角的关系式，以及平面镜转动角与微波发射角的关系式，并画出了对应的关系曲线图。对微波发射位置进行了测定实验。实验结果验证了上述参数关系式的准确性，表明其可以作为平面镜转动机构驱动控制的理论基础。
