Transmission Loss Prediction for the AN/TRC-97A Over a Tropospheric Scatter Path.
Abstract
This research investigates transmission loss predictions for a short range tactical troposcatter radio system. The analysis is based on the AN/TRC-97A radio set, but the conclusions reached should apply to similar troposcatter systems operating at frequencies from 4.4 to 5.0 GHz and over distances of 160 km or less. A general analysis of the troposcatter path is performed to determine the sensitivity of the transmission loss of the various phenomena which contribute to the loss. That component of the loss which is unique to the scattering process is studied in further detail and a modified scattering loss model is developed. A procedure for determining the coefficients of the scattering loss model based on observed transmission loss is described. A preliminary analysis of the path data available for this research is performed. It is found that the received power probability distribution for the observed paths does not agree with the theoretical distribution in all cases. Further, the available path data is seen to lack sufficiently detailed path geometry information to complete the analysis of the scattering loss model. Recommendations concerning data requirements and continued research are offered. (Author)
