为什么“卫星波束以近似平行的状态射入轴截面为抛物线的接收天线,经反射聚焦到焦点处”?带着这个问题,我们向老师请教.在老师的指导下,我们通过数学建模,给出了证明:
Why does the “satellite beam enter the parabolic receiving antenna in an approximately parallel state and is focused by reflection to the focal point?” With this question, we ask the teacher. Under the guidance of the teacher, we use mathematical modeling. Gives proof of:
