The 71-76 GHz and 81-86 GHz bands have the potential to provide ultrahigh bandwidth (gigabit per second [Gbps] data rates) point-to-point communications between a satellite and a ground station. However, one of the most crucial problems in achieving this communication link is the uncertainty of signal attenuation, phase distortion, and depolarization resulting from atmospheric absorption, scintillation, and meteorological effects (e.g., rain fade). High fidelity propagation models must be developed, statistically validated, and correlated to meteorological parameters and climatic regions as was done for the Ka-band in the 1990s to enable the Air Force to accomplish feasibility studies, systems engineering, and availability modeling to support future military satellite system architectures.
The objective of this research is to develop improved models to predict path attenuation, phase distortion, and depolarization, particularly at 71-76 GHz and 81-86 GHz. Key parameters affecting channel propagation must be identified and the functional relationship modeled.
Some of the goals of this research are (1) a model development of key communication channel properties (attenuation, phase distortion, depolarization); (2) identification of key parameters affecting channel properties (absorption, scattering, scintillation, humidity, moisture, hydrometers, rain-rate); and (3) simulations, comparison to current models
We seek applicants with backgrounds in communications theory, EM theory, or physics with understanding of radio wave propagation phenomena.
