HF propagation through actively modified ionospheres: Modelling and experimental results
Abstract
A computer modelling capability was developed for predicting the effects of localized electron density perturbations created by ionospheric chemical releases upon oblique, one-hop HF propagation paths. A three-dimensional description of the depleted or enhanced ionization, including formation, evolution, and drift are presented. The code uses a homing ray tracing technique to calculate the energy propagation paths through the modified ionosphere and hence can predict multipath effects.
