Ia. Molotkov et Yn. Cherkashin, SOME NONLINEAR EFFECTS OF WAVE BEAM-PROPAGATION IN THE IONOSPHERE, Journal of atmospheric and terrestrial physics, 56(11), 1994, pp. 1477-1481
The controllable, additional stratification of the F2 ionospheric laye
r resulting from the propagation of a powerful wave beam is establishe
d. The formulae showing the properties of a diagnostic beam injected i
n the same direction as the powerful beam, but shifted in frequency, a
re derived as a function of the powerful beam intensity and of the fre
quency shift. The theoretical results are completed with numerical est
imations.
