Abstract:

Interactions between the ionosphere and satellites are investigated, and it is shown that an ambient density perturbation in the satellites wake is produced. This perturbation has detectable scattering properties in the hf band that are related through several non-dimensional parameters to satellite size, shape and dynamics as well as the ambient medium. A pertinent experimental program is also specified. The scatter calculation is based on the Born approximation to the field-perturbation characteristics, and its range of validity as well as its accuracy is evaluated for this problem. As noted, scatter characteristics are analyzed in terms of non-dimensional parameters. Specific relationships are determined for independent viewing sites at Kwajalein Island and Rome, N. Y. The inadequacies in previous theoretical and experimental efforts are also discussed. Author
