Book Synopsis Rocket Investigations of the VLF Ionospheric Transmission Window by : Richard B. Harvey
Download or read book Rocket Investigations of the VLF Ionospheric Transmission Window written by Richard B. Harvey and published by . This book was released on 1973 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Receivers were flown in rockets from Eglin Air Force Base, Florida, Natal, Brazil, and Fort Churchill, Canada, to study the fields of very low frequency (VLF) waves propagating in the earth-ionosphere waveguide, and leaking through the ionosphere to altitudes of 500-600 km. Amplitude-height, group delay, and polarization profiles are given for signals from a number of ground based transmitters. A coherent propagation model is proposed and partially tested by calculating Doppler shifts. The model, extended with a full-wave computer program, allows wave-field profiles to be approximated theoretically. The extent to which some sample calculations agree with the observations is discussed. (Author).

Book Synopsis A Preliminary Rocket Investigation of Very Low Frequency Ionospheric Resonances by : R. E. Barrington
Download or read book A Preliminary Rocket Investigation of Very Low Frequency Ionospheric Resonances written by R. E. Barrington and published by . This book was released on 1969 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Javelin sounding rocket equipped with two large orthogonal dipole antennae, a VLF receiver and a swept frequency oscillator and pulser was flown at the Churchill Research Range in an attempt to stimulate and detect at least one of the natural resonances of the ionosphere that lie in the VLF band. The pulser and swept frequency oscillator were connected to one of the dipole antennae and the VLF receiver was connected to the second dipole. The amplitude and the rate of change of frequency of the signal coupled through the plasma from the oscillator to the receiver showed no observable change at frequencies in the neighbourhood of the lower hybrid resonance frequency. Average amplitude changes from sweep to sweep of greater than 40 dB were found as the aspect of the rocket changed. Immediately following the cessation of the signals from the oscillator, a burst of noise that had a lower frequency cut-off at the lower hybrid resonance was encountered on many sweeps. These results indicate that it is possible to stimulate, by artificial means, the lower hybrid resonance of the ionosphere, and to use the stimulated signals to determine the frequency of this resonance.
