T/CI 003-2021 Polarimetric Remote Sensing Techniques for Surface-Based Object Detection Standards

Scope

Scope: This standard specifies the data collection and management methods, content, processing flow, output formats, and quality control of surface-geological polarization remote sensing detection. This standard applies to the collection and management of surface-geological polarization data in multiple applications, including analyzing the polarization characteristics of surface-geological objects, constructing polarization instruments, and analyzing the physical and chemical characteristics of surface-geological objects, etc. Main technical content: 3. Surface-geological polarization remote sensing detection content 3.1 Basic principles Polarization, as a new remote sensing observation method and a supplement to conventional remote sensing, has the important physical characteristics of "enhancing weak light" and "attenuating strong light", greatly extending the detection range of both bright and dark areas in remote sensing. This capability is summarized as five major characteristics of surface-geological polarization remote sensing: multi-angle reflection physical characteristics, multi-spectral chemical characteristics, roughness and density structure characteristics, high contrast ratio filtering characteristics of information-background, and multiple scattering energy radiation transmission characteristics. In order to scientifically detect these polarization remote sensing characteristics of surface-geological objects, the following three principles must be adhered to: - Scientific feasibility principle: The detection purpose must be clear, the detection principle must be correct, the detection objects and detection methods must be selected appropriately, and the entire design concept must meet the basic scientific criteria of this discipline. - Single variable principle: Among the various factors controlling polarization information, keep other factors constant and only change one factor to observe its impact on the acquired polarization information. - Paral
