RADIATION ENVIRONMENT SYSTEM (RADIO-FREQUENCY TYPE).

Abstract

The report covers findings pertinent to establishing feasibility of a system capable of simulating radiation environments using radio-frequency techniques. Both radiation from initial bursts and from subsequent fallout are considered. Two basic techniques could conceivably be used as the basis for simulation, one based on electromagnetic field intensity, the other on the velocity of propagation of radio-frequency waves. Analysis reveals that systems based on electromagnetic field intensity are incapable of providing required accuracy. The required accuracy can be provided by two types of systems based on propagation velocity. Hyperbolic grid systems and direct distance measurement schemes both possess the required accuracy. For simulation purposes the hyperbolic system is preferred. A system can be derived which is capable of meeting the simulation objectives. A high degree of repeatability can be provided using methods established and proven by hyperbolic navigation systems. Requirements of the simulation allow simplification relative to existing navigation systems. (Author)
