RECOGNITION AND IDENTIFICATION OF EARTH SATELLITES AND SPACECRAFT
Abstract
This volume of the report consists of four appendices. The first three of these are concerned with the calculation of the flux distributions in infinite slab geometry for three radiations: gamma rays, neutrons, and heavy charged particles. The results of these calculations are then employed to find the counting rate at a detector that is on the opposite side of a semi-infinite slab from a source of monoenergetic monodirectional radiation. For each of the radiations noted above a counting rate equation is deduced that exhibits explicitly the dependence of the counting rate on the various parameters. These parameters include the strength of the source, the characteristics of the material composition of the slab, the geometrical factors and the characteristics of the detector. The fourth appendix discusses the magnetic field produced by a charged body moving through a plasma in the magnetohydrodynamic regime. Two models of the body, i.e., a point charge and a charged spherical shell, are considered, and the effect of finite sound velocity in the plasma is calculated. It is shown that while the major component of the magnetic field is non-propagating, a second propagating component is also produced. (Author)
