This problem is solved for the case of topside ionospheric sounding when the height distribution of electron density is monotonic. An analytical expression is obtained, which relates the variance of deduced parameters to the correlation function of errors in measured characteristics of sounding signals. The computer simulation is provided for errors in real height determination; in reconstruction of vertical velocities of plasma motion; and in effective electron collision frequencies for the measurements of virtual heights, Doppler shift, and radio wave absorption, respectively. Their dependencies on signal polarisation, working frequency range, and geomagnetic latitude of the observation point are determined. The obtained results are useful for planning plasma experiments using HF sounding technique.

Notes
The problem of RMS error determination is considered here in relation to the improvement of the accuracy and reliability of radio experiments dedicated to the determination of the ionospheric parameters measured by the vertical HF sounding. An analytical expression relating the variance of deduced parameters to the correlation function of errors in measured characteristics of sounding signals was obtained. Computer simulation is provided for errors in determination of all major ionospheric parameters. Their dependencies on signal polarization, working frequency range, and geomagnetic latitude of the observation point are determined. Obtained results are very useful for planning HF sounding plasma experiments.Full text available
