Abstract
The development of the Horus digital polarimetric phased array radar at the University of Oklahoma is providing opportunities to explore and develop a number of element-level calibration and performance enhancement techniques. As digital phased arrays provide convenient mechanisms for in-situ mutual coupling measurements, the Horus engineering team has been leveraging them to iterate and improve on previously-reported algorithms that seek to align and monitor the performance of each element. Here, these algorithms and initial performance results are summarized.
