抽象的。本文描述了一种新型的，空气寄宿的基于POD的毫米（MM）波长雷达。它的运行频率为94 GHz（波长为3 mm）。雷达的设计是在Ncar Gulfstream V Hiaper飞机上飞行。但是，它可以部署在其他设备齐全的飞机上。基于POD的配置占据了最小的机舱空间，并最大程度地提高了扫描覆盖范围。雷达系统能够在天顶和纳迪尔之间或扫描模式之间以凝视模式收集观测值。记录了记录反向散射信号的矩和原始时间序列的标准脉冲对估计。描述了雷达系统的设计和特性以及用于校准反射率和校正飞机态度和运动的多普勒速度的技术。可以将雷达部署在基于地面的配置中，该配置包含在具有高光谱分辨率LIDAR（HSRL）的20英尺运输容器中。在地面和飞行中对雷达进行了测试。收集了多普勒和极化测量的初步测量，并提供了示例。
Abstract. This paper describes a novel, airborne pod-based millimeter (mm) wavelength radar. Its frequency of operation is 94 GHz (3 mm wavelength). The radar has been designed to fly on the NCAR Gulfstream V HIAPER aircraft; however, it could be deployed on other similarly equipped aircraft. The pod-based configuration occupies minimum cabin space and maximizes scan coverage. The radar system is capable of collecting observations in a staring mode between zenith and nadir or in a scanning mode. Standard pulse-pair estimates of moments and raw time series of backscattered signals are recorded. The radar system design and characteristics as well as techniques for calibrating reflectivity and correcting Doppler velocity for aircraft attitude and motion are described. The radar can alternatively be deployed in a ground-based configuration, housed in the 20 ft shipping container it shares with the High Spectral Resolution Lidar (HSRL). The radar was tested both on the ground and in flight. Preliminary measurements of Doppler and polarization measurements were collected and examples are presented.
