Abstract:
The National Bureau of Standards has established extensive facilities for studies of tropospheric radio-wave propagation in the very-high frequency and ultra-high frequency portion of the frequency spectrum at Cheyenne Mountain, Colorado. These facilities include high-power continuous-wave transmitters on five frequencies, from 92 to 1,046 Mc. Continuously recording field-strength receivers are located at four fixed receiving locations ranging to 226 miles from Cheyenne Mountain, with provisions for semifixed recordings at Anthony, Kans., and Fayetteville, Ark., which are 393 and 617 miles, respectively, from the transmitter site. An extensive radio meteorological installation is located at Haswell, Colo., where accurate measurements of temperature, pressure, and humidity are made with electronic measuring devices, and refractive-index turbulence is measured with the microwave refractometer developed at the Bureau. These facilities are described and sample results are reported. The new theory of tropospheric propagation embodying the Booker-Gordon scattering principles as extended by Staras is related to the measurements.
