Abstract :
This paper will introduce a new technique for modeling sidelobe clutter in mountainous terrain, while expanding upon our previous work in modeling three-dimensional aspects of clutter. The method was developed, in part, to overcome the limitations of electromagnetic parabolic wave equation (PWE) models with regards to complex antenna patterns. This technique also produces a more accurate representation of the clutter versus our previous methods.
