An accurate geolocation of the radio frequency interference (RFI) sources is significant to effectively switch off illegal transmitters. In this study, utilizing the sparse property of RFI in the observed scene, a super-resolution RFI localization method based on compressive sensing is presented in synthetic aperture interferometric radiometer (SAIR). Numerical results show the presented method can...
People pay great attention on the indoor air pollution of public building now. Indoor environment of six university buildings (library, laboratory, classroom, dormitory, computer room and office) were measured with gas detector from March to May. The concentrations of total volatile organic compounds (VOCs) of these sites meet the "Indoor air quality standards "requirements of China. The...
Indoor air quality of the new building has become a major concentration in China. Volatile organic compounds (VOCs) in new buildings were investigated and factors significant to their presence were discussed. Concentrations of volatile organic compounds, temperature and humidity were measured in four new apartment buildings over 6 months following installation. Formaldehyde concentrations in the new...
Net ecosystem exchange (NEE) is a critical ecological parameter indicating the exchange of carbon dioxide between vegetation and atmosphere, which is widely used in the field of carbon cycle researches. It is common measurement by flux tower based on eddy covariance technique can only represent local status, however regional NEE is much more important. This paper introduces a spatialization method...
