The state of the land surface and the water cycle over the South and East Asia can be determined by space observation. New or significantly improved algorithms have been developed and evaluated against ground measurements. Variables retrieved include land surface properties, i.e. NDVI, LAI, FPAR, albedo, soil moisture, glacier and lake levels. Based on these biophysical parameters derived from microwave...
Monitoring crop areas is a key issue in remote sensing studies. A Crop Proportion Phenology Index (CPPI) model has previously been developed for estimation of winter wheat areas. Here we test the CPPI model in different areas using remote sensing data for varied kernel functions, including linear regression (LR), Artificial Neural Network (ANN), and Support Vector Regression (SVR). The differences...
Rapid detection of collapsed built-up structures is crucial for disaster mitigation in earthquake-affected areas. This paper proposes a method on detecting collapsed built-up structures using only post-event images. Its essence is to track and detect debris of collapsed built-up structures using features obtained through the derivative morphological profile. Experiments are carried out on images of...
Wireless tomography, a novel approach to remote sensing, is proposed in Part I of this series. The methodology, literature review, related work, and system engineering are presented. Concrete algorithms and hardware platforms are implemented to demonstrate this concept. Self-cohering tomography is studied in depth. More research will be reported, following this initiative.
to detect water constituents' concentrations and salinity of the Pearl River Estuary (PRE), we analyzed the spectral properties of water constituents and investigated the relationships between field water reflectance spectra and water constituents' concentrations based on the synchronous in-situ hyper-spectral data analysis. Two strong relationships were discovered (two linear fit described respectively...
The wind vector affects a broad range of naval missions, including strategic ship movement and positioning, aircraft carrier operations, aircraft deployment, effective weapons use, underway replenishment, and littoral operations. Furthermore, accurate wind vector data aids in short-term weather forecasting, the issuing of timely weather warnings, and the gathering of general climatological data. WindSat...
