Abstract : For an antenna in the ionosphere above the F layer, there is a cone of directions within which a radio signal coming in to the earth can reach the antenna. Computations have been carried out of the aperture of this conical pattern for an antenna height of 1000 km, and for different ionospheric conditions. The computations are compared to experimental determinations of the aperture made using the sweep-frequency receiver in the Alouette satellite to observe the radiations from the sun. (Author)
