摘要：

The National Radio Astronomy Observatory is engaged in two major new telescope projects. Each requires technological advances to meet the scientific requirements. The Green Bank Telescope is a fully steerable 100 m diameter filled aperture telescope for operation over the frequency range 300 MHz to 100 GHz. The Millimeter Array is a forty element interferometer of 8 m diameter antennas, with a goal of using 10 m or even 12 m antennas, for operation over the frequency range 30 - 850 GHz. The technical features being used to achieve the performance specifications are presented together with examples of the science that calls for these specifications. The current status of each project is also discussed.
