Abstract Mobile weather radars often utilize rapid-scan strategies when collecting observations of severe weather. Various techniques have been used to improve volume update times, including the use agile and multibeam radars. Imaging radars, similar in some respects phased arrays, steer radar beam software, thus requiring no physical motion. In contrast imaging gather data for an entire simultaneously within field view (FOV) radar, which is defined by a broad transmit beam. As result, provide rates significantly exceeding those existing mobile arrays. The Advanced Radar Research Center (ARRC) at University Oklahoma (OU) engaged design, construction, testing system called atmospheric (AIR). Initial tests performed with AIR demonstrate benefits versatility utilizing beamforming achieve high spatial temporal resolution. Specifically, point target analysis was using several digital techniques. Adaptive algorithms allow improved resolution clutter rejection compared traditional Additional experiments were conducted during two events Oklahoma. Several methods tested analyzed, producing unique, simultaneous measurements AIR.
