Development of a Minicomputer Atmospheric Noise Model.
Abstract
A practical but simplified atmospheric noise model for use in estimating system signal-to-noise ratios in micro-mini-computer based HF propagation prediction systems is presented. Numerical mapping techniques were used to represent worldwide atmospheric noise at 1 MHz in 24 numerical maps: one for each of six 4-hour time blocks (in universal time) and each of four 3-month periods. This representation results in a minimum reduction by one-fifth in the number of coefficients necessary in computer memory over that of an earlier model in which the map represented an entire twenty-four hour day.
