Book excerpt: The atmosphere can apparently be ionized to such a degree that the ground wave is disturbed, as a result of, for example, a nuclear event, and ionizing radiation of sufficient intensity to overcome the ion-ion recombination processes may cause the ions to accumulate near the surface of the ground. Gamma radiation from the fallout of a nuclear weapon may produce such ionization for a considerable time after the nuclear event. The problem is similar to that of terrestrial radio wave propagation via the ionosphere, except that in the former case the ionization has a maximum near the surface of the ground and decreases exponentially with altitude. In other words, we have an upside down ionosphere to consider. A new theoretical approach to such ground wave problems based on methods of numerical analysis has been developed for computer application. The computer computation concept is discussed and sample computations based on the fallout model profile are presented. A particular fallout model based on data given in the U.S. Atomic Energy Commission’s handbook on “The Effects of Nuclear Weapons” is considered in some detail, and the effect of an ionization profile (ion number density as a function of altitude) on the propagation of the ground wave is ascertained. A physically possible but not likely extra attenuation of 12 dB at 100 km distance is noted.

Download or read book Ground Wave Propagation in a Normal and an Ionized Atmosphere written by J. Ralph Johler and published by . This book was released on 1969 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground wave propagation in the presence of intense atmospheric ionization, such as may occur as a result of ionizing radiation from nuclear events, is studies. The influence of an enhanced dielectric constant for the atmosphere is also considered. It is concluded that extremely high ionization sources are necessary to produce sufficient ions to completely attenuate the ground wave because of the high ion-neutral collision frequency at the ground level. The analysis method is immediately applicable to the study of ground wave propagation in the ionized atmosphere of a planet of other celestial body, since this requires only the trivial but numerically significant modification of the radius of curvature of the ground. A computer program is presented which can calculate the ground wave in both the normal and the ionized atmosphere. The altitude above ground of either transmitter or receiver or both transmitter and receiver can be taken into account.
