Uncover Fully Ignored Vital Bathymetric Data Mysteriously Hidden in Digital Elevation Model Combining with Remote Sensing Imagery (Part 1: Methodology and Theoretical Interpretation)

摘要

This is an interdisciplinary research to uncover a miss-observed and very important phenomenon in remote sensing. The high valuable bathymetric data hidden in digital elevation models have completely been ignored by scientists and researchers including main organizations in the world for a long time. The contents have been classified into two parts to demonstrate them. In the part 1, the focus is on introducing a special technique of discovering bathymetric data of lakes and rivers by means of remote sensing Image processing and the fact of water depths found in seeking for a resolution to water pollution for a large scale inland lake. The further performance is in analysing causes starting from radar interferometry. The more attentions are paid to how the microwave emitted and received by antennas of synthetic aperture radar installed in satellites during its propagation and scattering back interacts with molecules of chemical compounds in water body using spectral analysis in spectroscopy such as Raman scattering, nuclear magnetic resonance combining with knowledge of quantum mechanics and physical chemistry. The causes of losing those data have been found from phase shifting interferometry during phase detection and terrain mapping. The outcomes of this research have proved a fact that the capacity of microwave detecting depths of water relies on molecular structure, communication and strength of external electromagnetic fields and bathymetric data could also exist near sea coast. Researchnot only offered difference between optical imaging and radar imaging but also established correlation of effectively using individual data.
