With the impending deployment of the new Open Radar Data Acquisition (ORDA) system at Phoenix, AZ, the Radar Operations Center (ROC) Operations Branch conducted a site visit to investigate persistent interference and clutter suppression issues. This initial operational assessment, calibration, and data collection effort was followed by a ROC Engineering Branch visit in which the team installed the Portable ORDA (Porta-ORDA). Level II data was collected using the Porta-ORDA platform and that data is compared to legacy data collected during the initial site visit.

Also discussed is the implementation of processing improvements that result from the on-going data quality analysis conducted at the ROC.
