Abstract: Predictions of tropospheric transmission loss over irregular terrain using the computer methods described by Longley and Rice (1968) are compared with measurements, to determine their limits of applicability and define the boundary conditions for their use. Area predictions for mobile systems where individual path profiles are not available are compared with measurements made with low antennas in Colorado, Ohio, Virginia, Wyoming. Idaho, and Washington. Point-to-point predictions for fixed antenna locations are compared with measurements for each of these paths and for a large number of propagation paths in various parts of the world.
Keywords: irregular terrain; tropospheric propagation; fixed point systems; mobile systems; prediction methods
