NOMOGRAMS FOR OBTAINING THE ARRIVAL ANGLE AND BEARING OF RADIO WAVES FROM MEASUREMENTS OF PHASE DIFFERENCE BETWEEN THREE STATIONS ARRANGED IN AN EQUILATERAL TRIANGLE

摘要

The nomographic procedures described here are devised for facilitating computation of values for wave arrival angles obtained from a 3-stotion receiver system. The original effort was conducted to simplify the resolution of the angle-of-arrival vector from component measurements made on a wideband "3-port" receiving system at the Electro-Physics Laboratories' field site(Ref. I). The particular 3-port con-figuration utilized three wideband, vertically polarized, monopole antennas placed at the apices of an equilateral triangle.
