New 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 2021 and has undergone a process of periodic software upgrades to augment its initial operating capabilities. This work describes the new capabilities of the ATD in support of engineering and meteorological research at the National Severe Storms Laboratory. 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.
