Abstract : -H-662701-A-4481-H-662701-A-44806(*ionospheric propagation, radio interference), (*radiofrequency interference, predictions), radio transmission, high frequency, regression analysis, real time, army operationsIonospheric sounder stations were set up at Fort Monmouth, NJ and Aberdeen Proving Ground, Maryland to form the terminals of a nominal 200 km path. Data were taken at each terminal in the vertical incidence (VI) mode and between the terminals in the short-path oblique incidence (OI) mode. A statistical model, previously developed for analysis of short-path ionospheric MOF data, was used to show that there was no significant difference between the short-path OI and VI data. The VI data was used in a near real-time forecasting scheme to provide short-path OI predictions 10, 30, 90, and 120 minutes in advance. Predictions were compared to observed OI data. (Author)
