摘要

l波段成像散射仪(LIS)由NASA/Goddard太空飞行中心作为RadSTAR计划的一部分开发,是一种机载成像雷达,结合了相控阵技术和数字波束形成技术,用于测量重要的科学参数。该仪器的工作频率为1.26 GHz,水平极化,并采用实时处理器,能够在+/-50度的扫描范围内合成多个波束。LIS在2006年5月和2007年1月分别在弗吉尼亚州德尔马瓦半岛上的NASA P3飞机上进行了飞行测试。在本文中,我们描述了RadSTAR系统,并对测试飞行期间收集的雷达数据进行了一些初步分析。

RadSTAR L-band imaging scatterometer- performance assessment
L-band Imaging Scatterometer (LIS), developed at NASA/Goddard Space Flight Center as part of the RadSTAR initiative, is an airborne imaging radar that combines phased array technology and digital beam forming techniques for the measurement of important scientific parameters. The instrument operates at 1.26 GHz, horizontal polarization, and employs a real-time processor capable of synthesizing multiple beams over a scan range of +/-50 degrees. LIS was flight tested in May 2006 and in January 2007 on board of the NASA P3 aircraft over the Delmarva Peninsula, VA. In this paper we describe the RadSTAR system and present some preliminary analysis of the radar data collected during the test flights.
