马萨诸塞大学正在实施一项试验台，以评估X波段的相控阵天气雷达偏振测量。该项目旨在确定电子扫描和相关的偏振误差对天气雷达测量指标的影响，如反射率因子(Z)、差异反射率(ZDR)、共极相关系数(ρhv)和线性去偏振率(Ldr)。雷神公司租借给马萨诸塞州大学的相控阵雷达将与一台机械扫描的极化X波段天气雷达一起操作。本文对X波段相控阵雷达天线的极化性能进行了初步预测。
The University of Massachusetts is implementing a testbed to evaluate phased-array weather radar polarimetry at X-band. The project seeks to determine the impacts of electronic scanning and associated polarization errors on weather radar measureables such as reflecitvity factor (Z), differential reflectivity (Zdr), co-polar correlation coefficient (ρhv), and linear depolarization ratio (LDR). A phased-array radar on loan to UMass by Raytheon will be operated in tandem with a mechanically-scanned polarimetric X-band weather radar. In this paper we describe initial predictions of the polarimetric performance of an X-band phased array radar antenna.
