这份报告综合了克莱姆森大学和斯坦福大学进行的研究，他们进行了一系列测量，以确定存在于四个频段的人造辐射，这些频段被非常不同的服务使用，即L1频段(1563.42 1587.42兆赫)、统一S频段(2025年2110兆赫)、2.4千兆赫工业、科学和医学频段(2400 2482.50兆赫)和被动传感频段23.6-24.0千兆赫。结果表明，测量数据在频段上有明显的差异，应该根据与每个频段相关的功能/规则来预期。GPS L1波段几乎没有陆地人造信号源，但ISM 2.4 GHz波段有大量的人造信号源，无论地点和时间如何。统一的S乐队根据不同的地点表现出不同的结果。被动传感波段不包含明显的人造辐射。
This report consolidates research carried out at Clemson University and Stanford University where a series of measurements were undertaken to identify the man-made radiation present in four bands used by rather different services, namely, L1 Band (1563.42 1587.42 MHz), the Unified S-Band (2025 2110 MHz), the 2.4 GHz Industrial, Scientific and Medical (ISM) Band (2400 2482.50 MHz), and the 23.6-24.0 GHz Passive Sensing Band. Results show that there were distinctive differences in the measurement data in the frequency bands, which should be expected based on the function/regulation associated with each. The GPS L1 Band had little to none terrestrial man-made sources, but the ISM 2.4 GHz Band had a large number of man-made sources regardless of the site and the time. The Unified S Band showed mixed results depending on the sites. The Passive Sensing Band does not contain appreciable man-made radiation.
