本文介绍了NRO 45 m望远镜的大型焦平面阵列接收系统（SIS 25-BEam Array Receiver System，简称BEARS）。这种新的阵列接收器使用SIS结，有25个单元。它可以在82 - 116 GHz的频率范围内工作。这一新系统的开发已接近完成。本文对整个系统进行了详细的描述，包括接收机、中频系统、新型频谱仪和遥控系统。文中还描述了系统的性能和均匀性，并给出了天文结果。
A large focal plane array receiver system for the NRO 45 m telescope (SIS 25-BEam Array Receiver System, or BEARS) is described. This new array receiver uses SIS junctions and has 25 elements. It can operate at the frequency range of 82 - 116 GHz. The development of this new system is almost complete. We describe about the whole system in detail, which includes the receiver, the IF systems, the new spectrometers and the remote control systems. We also describe about the performances and the uniformity of the system and show the astronomical result.
