空间引力波天线DECIGO(迪赫兹干涉仪引力波天文台)将提供对宇宙的丰富见解，特别是关于超大质量黑洞的形成机制、暗能量和宇宙膨胀的见解。在目前的概念前设计中，DECIGO将由四个干涉仪单元组成；每个干涉仪单元将由三个相距1000公里的无阻力航天器组成。由于DECIGO将是一项极具挑战性的任务，具有长基线的高精度编队飞行，因此在计划于2027年发射之前提高技术可行性是很重要的。因此，我们计划启动两项里程碑式的任务。DECIGO探路器(DPF)是第一次里程碑式的任务，DPF的关键部件正在进行地面和在轨测试。本文综述了DECIGO和DPF的概念设计和研究现状。
A space gravitational-wave antenna, DECIGO (DECI-hertz interferometer Gravitational wave Observatory), will provide fruitful insights into the universe, particularly on the formation mechanism of supermassive black holes, dark energy and the inflation of the universe. In the current pre-conceptual design, DECIGO will be comprising four interferometer units; each interferometer unit will be formed by three drag-free spacecraft with 1000 km separation. Since DECIGO will be an extremely challenging mission with high-precision formation flight with long baseline, it is important to increase the technical feasibility before its planned launch in 2027. Thus, we are planning to launch two milestone missions. DECIGO pathfinder (DPF) is the first milestone mission, and key components for DPF are being tested on ground and in orbit. In this paper, we review the conceptual design and current status of DECIGO and DPF.
