An ionospheric volume in the F layer subjected to high power high frequency illumination is observed to be an effective scattering medium for radio signals. Experimental results are representative of a field‐aligned scattering geometry. Scatter of the incident wave into electrostatic waves by these strongly field‐aligned density irregularities is considered. This model explains the large decreases in radio wave reflectivity seen during the ionospheric modification.
