Title:
METAL ION-BASED LASER RADAR FOR DETECTING WIND FIELD AND TEMPERATURE IN E-F REGIONS AND DENSITY, AND DETECTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/051680
Kind Code:
A1
Abstract:
A metal ion Doppler mechanism-based laser radar for detecting the wind field and temperature in E-F regions and density, and a detection method. The laser radar comprises a laser emission system (1), a telescope receiving system (2), and a signal acquisition and processing system (3); by using various laser devices and under the action of optical switches and a frequency converter, the laser emission system (1) outputs three-frequency-switched laser light for detecting metal ions; the combination of laser beam splitter mirrors, laser highly reflective mirrors and the like realizes laser emission in vertical, east (west), north (south) directions which are consistent with receiving directions of the telescope receiving system (2); the telescope receiving system (2) receives echo signals in three directions, processes the echo signals separately to obtain electrical signals, and transmits the electrical signals to the signal acquisition and processing system (3) in a unified manner, so that the temperature and wind field in the E-F regions and the density of a metal layer can be simultaneously obtained. The detection of wind field and temperature is implemented by a laser radar using metal ions as tracers for the first time, thereby providing a detection means for implementing high-precision detection of the wind field and temperature in E-F regions.
