Pagination or Media Count:
The report performs the mathematical analysis necessary to add divergence loss in differential form to the ray-trace program. The analysis is to pertain to a two-dimensional x, z plane formulation express intensity change in decibels be adaptable to 100, 10 000, 100 000 yard and longer ranges and include finite-difference approximations for numerical integrations.
