Comparison of Predicted VLF/LF Signal Levels with Propagation Data.

Abstract

The propagation of VLF(Very Low Frequency) and LF(Low Frequency) radio signals is an important factor when evaluating the performance of strategic communications. The accuracy of the prediction models is sensitive to the ionosphere profiles used in the analytic process. There are limited amounts of measured data, particularly at LF frequencies from which to derive these profiles. This technical report compares some measured data collected in the tri-Service program with predicted performance ranges to illustrate the current prediction capability and the need for improvement.
