The Combined Array for Research in Millimeter Astronomy (CARMA) was formed from the merger of three telescope arrays supported by the Division of Astronomical Science's University Radio Observatories (URO) Program: Caltech's Owens Valley Radio Observatory (OVRO) array of six 10.4-meter-diameter telescopes, the Berkeley Illinois Maryland Association (BIMA) array of nine 6.1-meter-diameter telescopes, and the University of Chicago's Sunyaev-Zeldovitch Array of eight 3.5-meter-diameter telescopes. CARMA currently achieves resolutions as high as 0.2 arcseconds at a wavelength of 1mm and, due to its heterogeneous combination of telescope diameters, provides excellent imaging over a wide range of angular scales. Science enabled by CARMA covers a broad range of astronomical topics, including star formation and molecular clouds, studies of external galaxies, and the investigation of solar system objects. CARMA is a pathfinder for the Atacama Large Millimeter Array (ALMA) and a pipeline for training experts in the field of millimeter interferometry to take full advantage of ALMA's capabilities for US astronomy. Users outside the CARMA collaboration receive 30% of all observing time.

毫米级天文研究联合阵列(CARMA)是由天文科学部的大学射电天文台(URO)计划支持的三个望远镜阵列合并而成：加州理工学院的欧文斯山谷射电天文台(OVRO)阵列由6个直径10.4米的望远镜组成，伯克利-伊利诺伊州协会(BIMA)由9个直径6.1米的望远镜组成，芝加哥大学的Sunyaev-Zeldovitch阵列由8个直径3.5米的望远镜组成。Carma目前在1毫米波长下的分辨率高达0.2角秒，由于其望远镜直径的不同组合，在广泛的角度范围内提供出色的成像。由CARMA促成的科学涵盖了广泛的天文学主题，包括恒星形成和分子云、外部星系的研究以及太阳系天体的调查。Carma是阿塔卡马大毫米阵列(ALMA)的探路者，也是培训毫米干涉测量领域的专家以充分利用ALMA在美国天文学方面的能力的管道。CARMA协作之外的用户获得所有观察时间的30%。
