REAL-TIME DATA ACQUISITION AND INTERPRETATION CAPABILITIES OF THE DYNASONDE .2. DETERMINATION OF MAGNETO-IONIC MODE AND ECHOLOCATION USING A SMALL SPACED RECEIVING ARRAY

Phase measurements by the Dynasonde are obtained for each echo from four spaced receiving antennas in a square array. The antennas are oriented along the array diagonals, and the phase values thus contain contributions identified with echo polarization and arrival angle. A unified procedure for separating these contributions is described. Ionograms with discriminated ordinary and extraordinary polarizations are displayed. ‘Skymap’ and ‘Gonionogram’ formats are also illustrated. This paper is not subject to U.S. copyright.
