Abstract:

Generally it is not feasible, or it is too costly, to conduct performance tests of a radio-communication system under the influence of actual atmospheric radio noise because of its nonstationarity and because of the difficulty in obtaining the desired noise conditions. Accurate simulation of desired conditions solves both difficulties. The device described here simulates HF atmospheric radio noise and is modeled after the available published characteristics of such noise, computer-analyzed samples, and empirical observations. The simulation is valid and accurate for the limited samples used. The basic concept of the device is sufficiently flexible that, with adequate statistical data, the several parameters could be adjusted so that the device could simulate any atmospheric radio noise condition likely to occur form ELF to VHF.
