NASA-LLIS-0381 : Lessons Learned - Antenna Test Difficulty at Air Force Eastern Test Range
سازمان: NASA - National Aeronautics and Space Administration (NASA)
کلید واژه: Performance Verification , Test & Verification , Test Facility
سال: 1995
زبان: English
قیمت: 290000 تومان
Abstract:
Although measurements at JPL suggested that the Voyager antenna system and its RF probe were not strongly affected by the building environment, the building environment at the test range location caused noticeable RF variations. When planning RF tests in different facilities, pathfinder tests should be conducted. Use RF probes with high directivity and shield the antenna from metallic surroundings that cause RF reflections.
