Update on an S-Band All-Digital Mobile Phased Array Radar

This paper provides an update on an S-band, polarimetric phased array radar designed to operate in the 2.7 - 3.1 GHz frequency band, which is being designed and built at the University of Oklahoma's Advanced Radar Research Center (ARRC). This is radar build 1 of 2 for our group in the S-band. Providing optimum radar flexibility, this phased array radar, known as Horus, is digital at every element and polarization.
