Untapped Capabilities of the Advanced Technology Demonstrator at the National Severe Storms Laboratory

The Advanced Technology Demonstrator (ATD) is located in Norman, Oklahoma and is the first full-scale, S-band, dual-polarization, active, electronically scanned phased-array radar (PAR) for weather observations. The ATD became operational in the spring of 2021 after reaching its Initial Operating Capabilities (IOC). Because the ATD IOC are somewhat limited, many untapped capabilities of the ATD will be demonstrated through a process of periodic software upgrades. Research conducted with the ATD will help determine the feasibility of PAR technology for the next generation of operational weather-surveillance radars in the US.
