摘　　要："FAST"可以根据待观测天体的位置进行反射面板的调整从而形成抛物面进行有效的信号收集。本文由方位角仰角确定被观察物体、原点、馈源舱所在曲面与基准球面之间的位置关系,根据反射面板调节幅度的限制,运用粒子群算法确定了抛物面的方程。最后根据空间解析几何的知识,求得以调整后抛物面为反射面的馈源舱的信号接收比为67.42%,以基准球面为反射面馈源舱接收比为5.26%。"FAST" can be adjusted according to the reflection panel of the object to be observed to form a parabola for efficient signal collection.In this paper, the position relationship between the observed object, the origin, the feeder compartment and the reference sphere is determined by the azimuthal elevation. According to the adjustment amplitude limit of the reflection panel, the parabolic equation is determined using the particle group algorithm.Finally, according to the knowledge of spatial analytical geometry, the signal reception ratio of the adjusted parabolic feeding compartment with the reflection surface is 67.42% and the feeding compartment with the reference sphere is 5.26%.
