Statistical Frequency-Distance Curves,Initial Model.

摘要

The report describes an initial computer program that produces statistical frequency-distance curves. The computer program has been developed as a tool for use by the frequency managers'community of OTP/IRAC. The statistical frequency-distance curves estimate the minimum distance separation that is required between a victim receiver and an interferer as a function of the frequency offset between them. The curves are parametric in the probability or percent of time that interference is permissible. The model uses statistical variations in antenna gain and propagation loss to compute the probability of interference. Appendices of the report describe the propagation loss and antenna gain models and the method used to combine them to produce the statistical frequency-distance curves. Operating instructions and several sample applications also are included as appendices.
