Abstract

The invention discloses a cabin type laser wind-measuring radar for measuring wind fields at different heights. The radar comprises a narrow line width seed light source module, a radar transceiver optical antenna module, and a signal receiving module. The narrow line width seed light source module comprises a narrow line width seed light source for outputting linear polarization continuous laser,a fiber optic amplifier with the input end connected with the output end of the narrow line width seed light source, an optical fiber circulator with the input end connected with the output end of the fiber optic amplifier, and a photoswitch with the input end connected with the first input end of the optical fiber circulator. The cabin type laser wind-measuring radar has the beneficial effects that the radar cost is lowered, and the radar wind field measurement capability is improved.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a nacelle-type laser wind measuring radar for measuring wind fields at different heights. Background technique [0002] The existing nacelle-type laser wind measurement radar products measure the wind field at the installation height, and then realize the measurement of the wind field information in front of the wind turbine, and complete the calibration requirements of the wind turbine. However, due to the non-uniform wind field in front of the wind turbine How to realize the measurement of the wind field at different heights in front of the wind turbine is a technical problem that needs to be solved urgently. Contents of the invention [0003] In view of the above problems, the present invention provides a nacelle-type laser wind radar for measuring wind fields at different heights. [0004] The object of the present invention adopts following technical scheme to rea...
