Ray tracing techniques are
employed to analyze the reflective characteristics of a path and to
simulate abnormal propagation conditions. The display operates in two
modes
Constant
Gradient A curved earth representation is used and all rays are drawn as
straight lines. The path of the reflected rays show the susceptibility of
the path to a specular reflection and helps identify the extents of the
reflective plane. In this mode, the signal variation as a function of an
antenna height can be displayed.
