为了对新一代DMSP F系列微波辐射计--专用传感器微波/成像仪/探测仪进行定标/验证，研制了一种机载圆锥扫描毫米波成像辐射计（CoSMIR）。CoSMIR是一种总功率辐射计，可在50-183 GHz的频率范围内测量9个通道的辐射。该仪器采用双轴万向节机构，以产生定期校准的圆锥扫描。它的扫描几何形状是软件可编程的，可以设计为满足实验的科学要求。2004年3月和12月，在加州沿海地区进行了一系列CoSMIR飞行，其中仪器被编程为同时获取圆锥和跨轨道扫描数据集。其中3月25日和12月2日的两次飞行包含白雪覆盖的塞拉山脉上空的部分，并被选中展示这种新仪器的新功能
An airborne Conical Scanning Millimeter-wave Imaging Radiometer (CoSMIR) was developed recently for calibration/validation of the new-generation DMSP F-series microwave radiometer, the Special Sensor Microwave/Imager/Sounder. The CoSMIR is a total-power radiometer that measures radiation at nine channels over the frequency range of 50-183 GHz. The instrument employs a two-axis gimbaled mechanism to generate the conical scan with periodic calibration. Its scan geometry is software programmable and can be designed to serve the scientific requirements of an experiment. A series of CoSMIR flights was conducted over the coastal regions of California in March and December of 2004, in which the instrument was programmed to acquire both conical and across-track scan data sets simultaneously. Two of these flights on March 25 and December 2 contained segments over the snow-covered Sierra Mountain Range and were selected to demonstrate the novel features of this new instrument
