Preliminary Chamber Measurements and a Status Report on the Development of an All-Digital Mobile Phased Array Radar

This brief manuscript provides an update on an S-band, digital-at-every-element 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. We are currently exploring a variety of nearfield panel measurements, which are presented in this paper. For instance, given that digital at every element affords vast array flexibility, new innovative concepts associated with mutual coupling calibration are being tested and verified.
