澳大利亚望远镜致密阵列(英语:Australia Telescope Compact Array,缩写为ATCA)是保罗怀尔德天文台电波望远镜,位置在澳州新南威尔士纳拉布里镇西方25公里。

这组望远镜由六架22米的同型碟形天线构成,通常以综合孔径的模式来产生电波影像。其中的五架碟形天线可以在长3公里的轨道上移动,第六架碟形天线位于3公长的主铁轨的最西端的末端。每个碟形天线的重量为270公吨。

这个致密阵列是澳大利亚望远镜国家设施网络的一部分,这个阵列经常与帕克斯天文台64米和靠近库纳巴拉班(澳洲新南威尔士)莫拉天文台的单一22米碟型天线连线,构成特长基线干涉仪阵列。 阵列功能:这些天线通过干涉技术同时工作时就拟合成一根更大的天线。让望远镜可以看见更为详细的天文图像信息。 效果显著的射电干涉技术代替了传统的通过精细电子器件和超级计算机以及复杂软件支撑运作的透镜望远镜。利用这个技术,天区里一个微小角度的图像信息能够在一个12h的时间段内形成。同样的干涉原理依然适用于所有6根天线遍及6km的天线阵,比如在一年中几个时间段内,这些天线阵可以同其他射电望远镜同时工作,就可以得到分辨率更加精细的图像。
