Abstract

The invention belongs to the technical field of active radar hyperspectral remote sensing, and discloses an unmanned aerial vehicle active radar hyperspectral detection system and method for marine environmental monitoring. The unmanned aerial vehicle active radar hyperspectral detection system comprises a laser emission system, an optical receiving system, a photoelectric detection unit, a data acquisition and storage unit, and a signal processing and control unit. According to the unmanned aerial vehicle active radar hyperspectral detection system, an unmanned aerial vehicle is used as a carrier to combine a laser radar and hyperspectral imaging on the same instrument, and visualized spatio-temporal distribution images and fluorescence hyperspectral data of target components are obtainedby remote sensing. A variety of marine parameters can be obtained through information extraction, and are used for measuring the oil-spilled pollution in seawater and the content of soluble organic matters and chlorophyll in seawater so as to realize the monitoring of water quality. The integration of multiple sensors provides reference for the identification and analysis of a target; and the system and the method improve the ability of information obtaining and the ability and accuracy of terrain analysis, reduce the cost of remote sensing detection and are conducive to the development of the field of spectral detection.

Description

technical field [0001] The invention belongs to the technical field of active radar hyperspectral remote sensing, and in particular relates to an unmanned aerial vehicle active radar hyperspectral detection system and method for marine environment monitoring. Background technique [0002] The main pollutants in coastal waters include leaked and discharged petroleum products and inorganic and organic substances contained in wastewater. The existence of these substances leads to changes in the composition of seawater, causing direct pollution of seawater or eutrophication of seawater, directly affecting the benign growth of animals and plants, and will have short-term or long-term effects on the surrounding environment of the ocean and the marine ecological environment. Mainly manifested in: oil spill in water, colored soluble organic matter, chlorophyll a, etc., which characterize the dynamic changes of marine environmental parameters. Therefore, the accurate and rapid detec...
