Abstract.
The algorithm for the numerical simulation of the propagation of the radio
beam in the lower part of the atmosphere of the Earth using both unperturbed
and perturbed, arbitrarily defined, the dependence of the refractive index of
the height of the atmosphere by setting different starting elevations
electrical axis of the antenna, including the negative ones was developed. We propose the method of calculating the initial
elevation angle of the radio beam, providing target illumination at a given
height and distances, including «the-horizon» on the basis of the algorithm. The dependencies of the final height of the
radio beam from the initial elevation of your dish for the technically
important characteristic of installation options for various antenna height
ranges to the target were demonstrated.
Keywords: refraction, refractive index, gradient of refractive
index, the radio beam targeting, the angle of elevation.
