Multilevel Tabulated Interaction Method Applied to UHF Propagation over Irregular Terrain

Conor Brennan and Peter J. Cullen

Page 1574.

Abstract:

A multilevel tabulated interaction method (TIM) is described for application to the analysis of exceptionally large two-dimensional (2-D) UHF terrain propagation problems. While standard TIM schemes offer extremely rapid solutions to terrain propagation problems on a medium to large scale ( 20 km), the computation times increase quadratically with problem size. For problems of extremely large size ( 100 km), we show how the adoption of the multilevel scheme proves beneficial, reducing computation times and restoring the TIM's computational advantage. Numerical results are provided illustrating the concepts introduced.
