Mobile radars are a familiar site in and around Norman and the National Weather Center. Typical mobile systems are dish oriented, meaning, they use a parabolic dish to steer the beam. In an effort to push the boundaries of severe weather observations, the Atmospheric Radar Research Center (ARRC) is developing a mobile X-band imaging radar called the Atmospheric Imaging Radar (AIR). The AIR is an advanced phased array radar, which has the ability to collect data over a large volume of the atmosphere simultaneously without the need for physical antenna rotation. This is achieved by utilizing a wide transmit beam and an array of passive receivers through which adaptive digital beamforming algorithms can be implemented. As a result, the data collected have an extremely high temporal resolution in addition to other advantages such as clutter mitigation, spaced antenna, etc. With the extremely high temporal resolution of the AIR, it is hoped that for the first time short-term phenomenon will be captured and their use in severe weather prediction will facilitate the next leap forward in radar technology, ultimately leading to longer lead times and fewer lives lost.
