Compact Reconfigurable High-Frequency Ultrahigh Frequency (HG-UHF) Antenna
Abstract
The goal of this research effort was the development of computer algorithms for the predication of radio wave propagation in forest or Vegetated environments. In addition, recognizing the need for measured data sets for validation of such modesi, two measurements Campaigns were conducted, one to determine path loss for near-Earth propagation and one which utilizes a unique, synchronized, long-range measurement system (the system has been tested to over a kilometer, and in principle will work over longer ranges), developed for this project, and which allos for the evaluation of both pathioss and frequency decorrelation. Since the stan of the project in May, 2001, significant progress was made towards achieving the project goal. A physics%based methodology was used, in which the actual physical scenario of a given propagatIon problem or environment is modeled. A description of this physics- based methodology and why this approach is applied is given in the final technical report. The impact of this effort on FOS and related programs is then discussed, followed by a brief summary of the project accomplishments. Completed work is then described. Where noted, expanded and detailed discussions of several of the developed algorithms is later given.
