Assessment of the accuracy of electron-temperature measurements by a high-frequency probe
Abstract
An analysis is presented of factors leading to the dynamic error of electron-temperature measurements in the ionospheric plasma by means of a satellite-borne high-frequency probe. The main components of this error are determined by the time lag of the probe and the variation of probe potential. Ways to reduce this error are suggested, including: (1) optimal selection of the radio-pulse repetition period; (2) reduction of the effect of time lag by extrapolation of the amplitude of detected pulses; and (3) reduction of the effect of variations of the intrinsic potential of the probe by interpolation of its values.
