Abstract:
This investigation of Propagation Medium RF Noise, has as its two primary objectives the deter-.mination of the character and magnitude of the noise introduced into radio communications systems by the propagating medium, and the development of techniques for reducing this noise by proper optimum antenna design. The study has been divided into four phases. In the first phase, the concet of the antenna as a space frequency filter was crystallized and some sample systems were studied in sufficient detail to define which characterist the noise are important from an antenna optimization standpoint. In the second phase, now under way, the available refractive index and radio propa gation data are being studied in order to deter mine the required noise characteristics. In phase three, the mathematical and conceptual tools for using this data in designing optimum antennas for specific purposes will be further developed. Phase four will consist of the appli cation of the results of the first three phases to the problems of specifying optimum antennas for various applications such as interference reduction, error reduction in high data rate systems, maximizing detection ranges, etc. If the results of phase two indicate that there is insufficient information about the noise avail able, definitive experiments to gather the re quired data will be proposed.
