Abstract:

O NOISE RATIO, Ground to air communications, TACAN, Distance measuring equipment, Guidance, Radio navigation, Very high frequencyThe report describes three computer programs for use in predicting the service coverage associated with airground radio systems operating in the frequency band from 0. 1 to 20 GHz. Power density, station separation and service volume programs are used to obtain computer-generated microfilm plots. These are 1 power density available at a particular altitude versus distance from a ground-based transmitting facility 2 the desired-to-undesired signal ratio, DU, available at an isotropic receiving antenna versus the distance separating desired and undesired facilities and 3 constant DU contours in the altitude versus distance space between the desired and undesired facilities. A detailed discussion of the propagation model involved and program listings are included in the appendices.
