Autonomous 2-D Near Field Measurements of EOS-04 Phased Array Antenna

In this paper, we present an automated test setup for 2-D near-field data acquisition of EOS-04 6m X 2m phased array antenna. We demonstrate how the automated positioning of the probe antenna in 2-D raster scan was achieved covering all the desired grid points and the corresponding data acquisition at each such position. Using this automation, 2-D near field transmit and receive mode imaging data was acquired to generate far-field patterns via holographic back projection technique.
