By use of computer simulation, it is possible to predict the effect of traveling ionospheric irregularities upon the data obtained by HF sweep- frequency ground-backscatter sounders. The simulation process makes use of an ionospheric model in which radio rays are traced to determine the time distribution of energy along the distant ground after skywave travel. Subsequent computation yields a synthetic record of the echo amplitude as a function of radio frequency and time delay, much like the experimental data. The degree of realism achieved is limited primarily by the need for economy the process used here is a simplified version of one previously described Ref. 1.
