Electron temperature measurements by incoherent scattering in the presence of strong small scale temperature irregularities

Abstract The results of electron temperature measurements by incoherent scattering have been considered under the conditions of existence of strong small scale temperature irregularities in the F-region of the ionosphere. A method to determine such local temperature enhancement from the analysis of the mean square error in the ACF fitting and the total scattered power of the ISR signal is pointed out.
