Book excerpt: A theoretical investigation is made of a possible method for determining electron densities and collision frequencies in the ionospheric D-region. This by means of an experiment involving the simultaneous measurement of the amplitudes of two radio waves of different frequencies, as a function of height, propagated from the ground to a rocket. It is hypothesized that the two frequencies, can be used to recover at each height of interest the two unknown quantities, electron density and collision frequency. It is shown, however, that for any two propagation frequencies below the gyro frequency this method fails. It is shown also that these results are consistent with those that might be obtained using the WKB approximations based on the roots of the Booker quartic. An error analysis of the single frequency method for determining electron densities assuming a single collision frequency model is also presented. (Author).

This book was released on 1973 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was undertaken to investigate the existence and properties of waves guided under the D-layer in low-loss Whispering Gallery or earth-detached modes at MF to LF. These low-loss paths are the result of focusing of rays reflected below the curved ionosphere, together with a marked decrease in ionospheric reflection loss at the highly oblique incidence angles obtainable only from high altitudes. Theory and calculations indicated an enhancement of this phenomenon during ionispheric disturbances and suggested a feasibility test. A low-power transmission experiment lasting over 30 hr was successfully conducted between balloons separated by 1000 miles at an altitude of 35 km on 220 and 440 kHz. Signals were received on the balloon path over most of the day and night. Total path attenuations varied from 3 to 30 dB below free space. Maximum signal height gains ranging from 40 to 60 dB relative to an equivalent ground-to-ground path were measured. (Modified author abstract).
