Scientific paper

The newest, major instrument development in the NSF Upper Atmosphere Facilities Program is the Advanced, Modular, Incoherent Scatter Radar (AMISR) now operating at the Poker Flat Research Range in Alaska. Two additional AMISR radars are being produced for deployment at the Resolute Bay Observatory, on Cornwallis Island, Nunavut, Canada (invariant latitude 81 degrees). The AMISR concept applies phased array radar technology and internet connectivity to the 40 year old incoherent scatter radar (ISR) research field. Advantages are primarily in remote operations and data viewing and inertialess beam steering. Prior to this application of electronic beam steering, ISRs were limited to a few pointing positions or they required minutes to reposition the radar beam. Limited temporal resolution in the measurements due to the antenna movement time is consequently eliminated. Although not a true analogy, this major ISR measurement improvement was similar to comparing measurements using a photometer with those made with imagers. This talk will focus on how best to exploit the potential of electronic steering as well as remote operations.
