Abstract

The present invention provides a space-borne atmospheric and ocean high repetition frequency laser radar system and detection method, including a high repetition frequency laser radar installed on a satellite, the high repetition frequency laser radar includes a three-wavelength laser emission subsystem, and a three-wavelength laser emission subsystem The optical axis adjustment subsystem electrically connected to the system, the receiving optical subsystem arranged on the side of the three-wavelength laser emitting subsystem, and the integrated control and signal processing subsystem electrically connected to the three-wavelength laser emitting subsystem and interacting with the satellite platform telemetry and remote control . In order to solve the problem of comprehensive observation of air, sea surface and underwater, the present invention provides a space-borne atmosphere and ocean high-repetition-frequency laser radar system and detection method. The space-borne system is based on high repetition-frequency multi-wavelength laser emission and photon simulation channel The method of collaborative detection can realize the simultaneous acquisition of global atmospheric, sea surface and underwater environmental information.

Description

technical field [0001] The invention relates to the technical field of measurement and testing, in particular to a spaceborne atmospheric ocean high repetition frequency laser radar system and a detection method. Background technique [0002] Clouds, aerosols, etc. are the main factors affecting the earth's radiation, and the main factors affecting the global climate and weather changes. Through stellar cloud-aerosol detection, the vertical profile of the global aerosol horizontal flux can be inverted, which is of great significance to meteorological and climate research. Shallow water bathymetry is an integral part of ocean surveying and mapping, which can provide important basic data for nautical charting, navigation safety, ocean delimitation, port construction and marine fishery. The remote sensing method that realizes high-precision direct measurement of water depth on the platform can obtain high-precision nearshore topographic data, water depth data, and changes in t...
