An Analysis of Two Problems Related to Over-the-Horizon Detection in the HF Band.

Abstract

A 21 -dB discrepancy between theory and experiment concerning Bragg scattering of HF ground waves by a rough sea is analyzed and resolved. In addition, a new and more efficient method of non-dimensionalization is proposed for the quantities of radio propagation in the HF band that could be adopted by all electromagnetic and acoustical wave bands of propagation. It is especially useful in the application of the Norton-Barrick concept of 'basic transmission loss.' (Author)
