HF ground wave propagation over forested and built-up terrain
Abstract
An integral equation method is presented for computing the vertically polarized field strength over irregular terrain which is covered with forest, buildings, or snow. The terrain cover is modeled as an equivalent slab, and a general computer code, WAGSLAB, is developed. Numerous special cases are treated analytically, and comparisons are made with numerical results from WAGSLAB.
