补充资料:连续和非连续孔径射电望远镜
射电望远镜因接收天体射电的天线孔径的构成方式不同,而有连续孔径和非连续孔径之分。连续孔径射电望远镜是射电望远镜的一种最简单的类型,其天线孔径为接收单元所布满,因而天线增益和分辨率全由天线孔径的实际尺寸和形状决定。这类望远镜天线孔径可以有各种形状,如通常的抛物面、球面、抛物柱面、抛物带形反射面等。某些由分立天线(如偶极子天线、裂缝波导等)组成的天线阵,当阵元间距不大于半波长时,由于电场强度方向图和连续面电流分布的场强方向图相似,也被认为是连续孔径射电望远镜。这种情况更常见于线孔径或米波、十米波段的偶极子阵。非连续孔径射电望远镜是天线结构只分布在孔径部分面积内的望远镜,通常由多个天线组成。栅式干涉仪、复合射电干涉仪、栅十字、 T形栅、圆阵、圆环以及综合孔径射电望远镜等都是。这种望远镜的分辨率由天线范围(设想的孔径)的外尺寸决定,而总的天线增益或灵敏度,则取决于全部天线单元面积的总和。图中a所示的连续孔径天线可认为由N个单元面积组成,经天线传至接收机的信号是各单元反射信号的迭加,连续孔径射电望远镜通过焦点处的馈源自动得到这种迭加。由于二单元A、B信号的迭加效果等效于处在A、B的相关干涉仪输出,非连续孔径射电望远镜正是基于这个原理,在省去孔径一部分的情况下,保留连续孔径各单元间的全部间距和取向,如图中b所示的"骨架式"射电望远镜,或者依观测需要对这些间距和取向进行有限的采样(各种干涉阵),甚至用不少于2的有限天线依次采样后进行处理;图中c是综合孔径望远镜。
