الوصف: Interest in the W & V-bands of the radio frequency (RF) spectrum has become steadily more desirable for system designers due to the ever increasing need for greater communication bandwidths and higher data rates. The 40 GHZ to 110 GHz range that constitutes the W & V-bands provide a unique solution to both of these current demands by providing a bandwidth nearly double that of all current RF frequencies in use. To date, this range has only been used for point to point satellite and short link communications meaning these bands have remained largely unexplored and undeveloped. To capitalize on the untapped benefits of these bands, research must be conducted into the nature of propagation and the effects the atmosphere imbues upon it in the form of attenuation and depolarization at such frequencies. To conduct this research and model these effects, the W & V-band Terrestrial Link Experiment (WTLE) experiment has been implemented. This experiment consists of two continuous wave beacon lens antennas located on the crest of the Sandia Mountains in Albuquerque, New Mexico. The V-band transmitter operates at a frequency of 72 GHz with a half power beam width (HPBW) of 3 degrees, a directivity of 35 dBi, and an estimated radiated isotropic power of 40 dBm. The Receiver is located 24 km away from the transmitter on the roof of the COSMIAC research center in Albuquerque, NM, and consists of two 0.5 m Cassegrain Reflectors that observe both co- and cross-polarization. In addition to the antennas, disdrometers and weather stations are located at both the receiver and transmitter locations. These stations provide atmospheric and precipitation data. Using the received power and collected atmospheric data at both locations, the atmospheric properties’ profiles along the radio path are constructed using interpolation and variation statistics between the two sites. With these profiles the attenuation due to dry air gases and the liquid water content through any present cloud can be calculated, and these two ...
