A high efficiency, low cost pollution air monitoring system based on space-borne terahertz radiometer is proposed. The radiometers are fixed on the MEO satellites on GPS or BDS. Four operating frequency point of the radiometer are chosen to monitor SO2 and NH3 and the design scheme is shown. The diameter of radiometer Cassegrain reflector antenna is 1,000mm. After reflection, the radiation is splitted...
Soil moisture is a critical factor in cosmopolitan meteorological and hydrological processes. Microwave remote sensing brightness temperature is sensitive to soil moisture through the effects of moisture on the dielectric constant and hence emissivity of the soil [1]. It was found that the brightness temperature at L-band is useful for retrieving near-surface soil moisture [2–3]. The Soil Moisture...
Government information resource is the foundation of e-government, and government information resource allocation system is the key factor that affects sustainable development of e-government. At present, a lack of the consolidated mode in government information resource allocation exists universally. The primary reason is that consolidation and formalization of research on government information...
