ELEVATION ANGLE OF ARRIVAL DETERMINATION IN THE WULLENWEBER RDF SYSTEM.
Abstract
The problem of determination of the elevation angle of arrival of ionospherically propagated high frequency radio signals with circular antenna arrays has been investigated through the technique of digital simulation. A system that is believed to be practicalbe is proposed; its implementation requires the use of modern digital data processing techniques and computer facilities. The system combines, by phasor addition, signals on opposite sides of the array from the azimuthal direction of arrival of a signal. The apparent result is a set of 'phantom' antennas. Certain selected pairs of these antennas are then used as interferometers, and the results of 8 to 10 such calculations are averaged in a suitable manner. Uses of this information are proposed.
