Use of active and passive satellite remote sensing from the NASA A-Train to investigate the relationship between cloud structure and hurricane intensificationHurricane intensity forecast accuracy is extremely important in order to take necessary precautions for landfall events. Good intensity forecasts ...
The Caspian and Aral seas are chosen as main study areas. The Caspian Sea evolution is primarily climate driven, while for the Aral Sea there is a mix of anthropic and climate factors. We analyze ice cover conditions using a novel method that combines active and passive satellite measurements ...

SMAP(Soil Moisture Active and Passive)卫星数据下载 SMAP(Soil Moisture Active and Passive) 是美国的地球观测卫星之一,2015年1月31日发射升空。从名字就可以知道,SMAP主要为了观测土壤水分,并且有主动的传感器和被动的传感器。主动的传感器是L波段雷达,被动的传感器是L波段微波辐射计。计划中,雷达和辐射计各自生产3...
The comparison of accuracy of artificial satellite's observations by laser radar "Interkosmos" and tracing camera AFU-75 EA Yurov - 《Journal of the Electrochemical Society》 被引量: 18发表: 1986年 On the accuracy of a passive or active satellite position obtained by the AFU-75 camera. M ...
This paper describes a novel technique of ocean surface vector wind measurement using active and passive microwave sensing from a satellite. For over a decade, satellite microwave scatterometers have remotely sensed ocean wind vector (speed and direction) by measuring ocean radar backscatter (sigma-0...
2.4. Satellite data For inter-comparison, multiple satellite remote sensing datasets including both active and passive remote sensing were incorporated. Sentinel-1 is a satellite platform with an active radar. Sentinel-2, Landsat-7 and -8, and MODIS are satellite platforms with passive optical senso...
This study assesses two approaches to combine observations from active and passive satellite microwave instruments in a soil moisture data assimilation sys... J Kolassa,RH Reichle,CS Draper - 《Remote Sensing of Environment》 被引量: 10发表: 2017年 Surface Wave Tomography of the Central Alps: Mer...
Here we show that active and passive spectrum sharing above 100 GHz is feasible by introducing and experimentally evaluating a real-time, dual-band backhaul prototype that tracks the presence of passive users (in this case the NASA satellite Aura) and avoids interference by automatically switching...
