我们介绍了一种最近开发的低成本，低质量，便携式L波段辐射计的空中应用无人机或地面应用。该辐射计已在多旋翼无人机上进行了测试，并在瑞士达沃斯-拉雷特遥感场进行了冬季积雪测量。辐射计测量双线性极化，具有约0.15 K的亮度温度分辨率为1秒的积分时间，和天线具有37度的半功率全波束宽度。组合系统的质量为3.8kg，功耗小于3 W。我们目前的天线和辐射计仪器，并从这些测试阶段的初步结果。
We introduce a recently developed cost effective, low mass, portable L-band radiometer for aerial applications on drones or for ground-based applications. The radiometer has been tested on a multicopter drone and for a winter seasons measuring snow at the Davos-Laret Remote Sensing Field Site in Switzerland. The radiometer measures dual-linear polarizations, has a brightness temperature resolution of about 0.15 K for 1 sec integration time, and the antenna has a half-power full beamwidth of 37 degrees. The mass of the combined system is 3.8 kg and the power consumption is less than 3 W. We present the antenna and radiometer instrument, and initial results from these test phases.
