High-Frequency Skywave Signal Power Measurement System
Abstract
The objective of this study was to verify high-frequency (HF) models for prediction of signal strength, signal-to-noise ratio, and circuit reliability. We derived a model of the short-term variability of signal strength. We established a transmission path for making high time resolution measurements of received power and transmission loss and used collected data to verify current models and develop new models. A transmission circuit was established between Forsyth, Montana, and Imperial Beach, California. Transmitting and receiving systems were designed and built. Software was developed for computer control of both transmitting and receiving systems. Measurements of received power at three selected frequencies in the HF band was begun in late December 1993.
