Specification for HF Lowest Usable Frequency (LUF) Model
Abstract
This report documents a high frequency (HF) lowest useable frequency (LUF) model called LUF. Developed at the Naval Ocean Systems Center, this semiempirical model permits simplified HF propagation predictions to be performed in near-real-time. The model predicts the LUF for arbitrary input values of receiver/transmitter position, date, time (UT), X-ray flux level, transmitter power, transmitter and receiver antenna type, transmitter and receiver antenna bearing, and required signal-to-noise ratio. Several algorithms are contained in the model to describe the dependence of the LUF on these input parameters. An appendix contains the computer FORTRAN 77 code required to implement the fundamental features of this model.
