- W1489753574 abstract "Abstract : Charts showing the relationship of range, height, and initial elevation angle of the rays from an earth-based antenna have been machine-computed and machine-drawn. The refracted (curved) ray paths are represented on the charts as straight lines, which facilitates plotting radio and radar vertical-plane coverage diagrams. The negative-exponential model of tropospheric refractivity has been assumed, although the method permits any model representable by a piecewise-continuous function to be used. Charts have been made for various systems of range, height, and angle units with equal and unequal range and height scales, with both linear and nonlinear scales, and for both small and large maximum range and height." @default.
