Abstract:

The use of parabolic wave equation codes to model tropospheric radio propagation is rapidly gaining popularity. To properly implement these powerful techniques into radar performance assessment models, requires a detailed understanding of the inherent errors in the parabolic approximation. This paper examines three major sources of error in split-step parabolic equation solvers 1 approximation of the elliptic wave operator by a parabolic operator, 2 truncation error in the formal parabolic solution, and 3 truncation error in the split-step operator. These errors are discussed in the context of operational codes.
