Some aspects of ionospheric drifts using partial and total reflections from the lower ionosphere

摘要: Two different aspects of ionospheric drifts are discussed in this paper. The effect the receiver triangle size on drift parameters derived from full correlation analysis is investigated, when partial reflections altitudes near 90km used. It found that, for frequencies 2 MHz, scale diffraction pattern ground order 100 m, and that show little dependence aerial separations greater than m. In addition, a number records obtained using both total have been analysed by dispersion method to look any systematic variation velocity with fading frequency. shown present only minority records, but it occurs more frequently reflection examples totally reflected waves E-region. Some possible interpretations result discussed.
