SAGE and Maximum Entropy Algorithmic Comparison for adaptive antenna array calibration

Abstract

Abstract-

Statistical techniques and algorithms applied in satellite communications antenna arrays for direction of arrival estimation and calibration

“… Gain: 14 dB Each antenna is followed by an outdoor housing box which includes a coupler, for test signal injection calibration, an RF filter and an LNA. The hardware is shown in the next photographs: The next table shows a summary of some parameters of the RF elements: 9 Cobhan Antennas, AMHS1.7-25R"D1 Datasheet In order to reduce the number of cables, the LNAs have been fed using Bias Tees. Prior to the LNA, a Transmission Reject Filter has been installed, so as to prevent saturation from the main antenna transmission.…”
