Joint retrieval of vegetation status from synthetic aperture radar (SAR) and optical data holds much promise due to the complimentary information in two wavelength domains. SAR penetrates canopy includes about water soil vegetation, whereas contains amount health leaves. However, inherent complexities combining these sources there has been relatively little progress joint over canopies. In this...
Over the years, remote sensing technology has become an important means to obtain accurate agricultural production information, such as crop type distribution, due its advantages of large coverage and a short observation period. Nowadays, cooperative use multi-source imagery new development trend in field classification. In this paper, polarimetric components Sentinel-1 (S-1) decomposed by mode...
Accurate land cover mapping is important for urban planning and management. Remote sensing data have been widely applied mapping. However, obtaining classification via optical remote alone difficult due to spectral confusion. To reduce the confusion between dark impervious surface water, Sentinel-1A Synthetic Aperture Rader (SAR) are synergistically combined with Sentinel-2B Multispectral Instr...
Introduction: Lymphoscintigraphy is imaging of the lymphatic system and has been integrated into the sentinel node mapping procedures. Lymphoscintigraphy usually encompasses early or delayed static images. However, immediate dynamic imaging of the lymphatic basins and tumors has also been used as an adjunct lymphoscintigraphy imaging. The aim of this study was ...
امروزه با پیشرفت تکنولوژی و اهمیت بحث تولید مدل ارتفاعی رقومی زمین از تمام نقاط کشور، می‌توان به لزوم استفاده هرچه بیشتر از سنجش از دور ماهواره‌ای پی برد. یکی از ارکان اصلی سنجش از دور ماهواره‌ای، سنجش از دور راداری می‌باشد. در سال</st...
