摘要移动天气雷达在收集恶劣天气观测资料时，经常采用快速扫描策略。已使用各种技术来改进体积更新时间，包括使用敏捷和多波束雷达。成像雷达在某些方面类似于相控阵，通过软件控制雷达波束，因此不需要物理运动。与相控阵相反，成像雷达在雷达的视场（FOV）内同时收集整个体积的数据，该视场由宽发射波束限定。结果，成像雷达提供的更新速率显著超过现有的移动的雷达（包括相控阵列）的更新速率。俄克拉荷马州大学的高级雷达研究中心（ARRC）正在设计、建造和测试一种称为大气成像雷达（AIR）的移动的成像天气雷达系统。与AIR进行的初步测试证明了利用波束形成技术实现高空间分辨率的好处和多功能性。
AbstractMobile 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 of agile and multibeam radars. Imaging radars, similar in some respects to phased arrays, steer the radar beam in software, thus requiring no physical motion. In contrast to phased arrays, imaging radars gather data for an entire volume simultaneously within the field of view (FOV) of the radar, which is defined by a broad transmit beam. As a result, imaging radars provide update rates significantly exceeding those of existing mobile radars, including phased arrays. The Advanced Radar Research Center (ARRC) at the University of Oklahoma (OU) is engaged in the design, construction, and testing of a mobile imaging weather radar system called the atmospheric imaging radar (AIR). Initial tests performed with the AIR demonstrate the benefits and versatility of utilizing beamforming techniques to achieve high spatial...
