STUDIES OF RF SCATTERING PROCESSES FROM IONIZED UPPER ATMOSPHERIC PERTURBAIONS.
Abstract
A special study is made of negatively shifted Doppler radar signals observed following high-altitude, high-explosive detonations. Suggested causes of these negatively shifted signals are presented. The data obtained during 3-electron affinity chemical releases in the F-region are given special study. A qualitative model is suggested which explains some of the observed data. Effects on other electron affinity release seem far more complex and do not seem to be explained well by a simple model. Quantitative cross-section estimates are made. A study is made of the criteria of importance to the use of continuum hydrodynamics at high altitudes. A decision criterion is suggested. A theory is developed which predicts altitude limits on the generation of air shock waves. The theory also predicts quite well equilibrium-high-explosive radii observed in the altitude region of 90 km to 120 km and in other tests which have been applied. The theory also seems to predict fairly well effects observed on events Fanny and Gilda. (Author)
