Abstract

A portion of the large Adelaide MF/HF antenna array has been used in conjunction with a new, 25 kW solid-state transmitter to conduct electronic beam-steering experiments. Thirty of the array's refurbished, independently-phased antennae were connected to the 10 power amplification (PA) modules in groups of three to form a steerable beam with a one-way half-power half-width of 5 degrees. Phase propagation errors in the receivers were determined and used to enable accurate direction finding and interferometric studies to be conducted. In this paper, new methods of determining the aspect sensitivity and three-dimensional linear wind field in the mesosphere and lower thermosphere (60 - 100 km) are introduced.
