本文介绍了由 NASA 仪器孵化器计划 (IIP) 资助的高空成像风雨机载剖面仪 (HIWRAP) 的开发。 HIWRAP 是双频（Ka 和 Ku 波段）、双波束（30 度和 40 度入射角）、锥形扫描、多普勒雷达系统，设计用于在高空（65,000 英尺）全球鹰无人机系统 (UAS) 上运行。它采用固态发射器以及新颖的脉冲压缩方案，使系统的尺寸更加紧凑，重量更轻，功耗更低，并且最终成本比目前用于降水和多普勒风测量的雷达要低得多。通过结合 Ku 和 Ka 波段的测量，HIWRAP 将能够通过测量云和降水的体积反向散射来成像风。
This paper describes the development of the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) which is funded under the NASA Instrument Incubator Program (IIP) . HIWRAP is a dual-frequency (Ka- and Ku-band), dual-beam (30deg and 40deg incidence angle), conical scan, Doppler radar system designed for operation on the high-altitude (65,000 ft) Global Hawk Unmanned Aerial System (UAS). It utilizes solid state transmitters along with novel pulse compression scheme that will result in a system that is considerably more compact in size, lighter in weight, less power consumption, and ultimately cost significantly less than radars currently in use for precipitation and Doppler wind measurements. By combining measurements at Ku- and Ka-band, HIWRAP will be able to image winds by measuring volume backscattering from clouds and precipitation.
