Abstract

The invention relates to a separate measurement device of polarizing remote sensing place-gas information based on a neutral atmosphere point. The separate measurement device comprises a polarization sensor device, a polarization sensor machine platform, a control unit and a computer, wherein the polarization sensor device is fixed on the polarization sensor machine platform; the control end of the polarization sensor device is connected with the control unit to carry out data collection and control; the control unit is connected with the computer, and carries out communication of data and a control signal. Different from a common remote sensing method, the separate measurement device mainly utilizes an atmospheric window to limit surface observation, can be widely applied to an atmospheric correction technology and an earth observation utility system for aerospace polarizing remote sensing in surface target observation.

Description

technical field [0001] The invention relates to a device for detecting the earth's surface through polarization remote sensing technology, in particular to a measuring device for separating earth-atmosphere information based on polarization remote sensing at an atmospheric neutral point. Background technique [0002] Polarization remote sensing is an emerging earth observation method that has attracted much attention recently. It provides new and potential information for remote sensing targets by detecting polarized light reflected by the atmosphere or ground objects. Due to the strong polarization of atmospheric particles, polarization remote sensing can detect the atmosphere effectively. However, this strong polarization of the atmosphere also leads to the fact that when the spaceborne polarization sensor detects the earth's surface, the signal received by the sensor is mainly the polarization information of the atmosphere, and the polarization properties of ground object...
